Abstract

In 1974 an accelerator of deterium, namely neutron generator NA-3-C was put into operation and in 1982 another accelerator of electron Microtron MT-17 started its work in the Institute of Physics. Though very modest these accelerators are useful for developing countries as Vietnam in both Nuclear Physics Research and Training. In this report we present some results obtained in studies on Nuclear Data, Nuclear Reactions as well as nuclear activation analysis methods. We also would like to discuss about the possibilities of collaboration in the future.

Compilation of isomeric ratios of light particle induced nuclear reactions
2023, Atomic Data and Nuclear Data Tables
Experimental isomeric ratios of light (A $\leq$ 4) particle-induced nuclear reactions were compiled for the product nuclides having metastable states with half-lives longer than 0.1 s. The experimental isomeric ratio data were taken from the EXFOR library and reviewed. When an experiment reports isomer production cross sections instead of isomeric ratios, the cross sections taken from the EXFOR library were converted to the isomeric ratios by us. During compilation, questionable data (e.g., preliminary data compiled in EXFOR in parallel with their final data, sum of isomer production cross sections larger than the total production cross sections) were excluded. As an application of the new compilation, goodness-of-fit was studied for the isomeric ratios predicted by the reaction model code TALYS-1.96. A text file and plots of the compiled isomer production cross sections and isomeric ratios are provided as supplemental materials.
Activation cross sections for reactions induced by 14 MeV neutrons on natural titanium
2023, Applied Radiation and Isotopes

The excitation function of default input parameters greatly underestimates the experimental data above the incident energy of 11 MeV, while the excitation function of adjusted optimal input parameters can reproduce the experimental data in the 12.5–15 MeV incident neutron energy range. For the 48Ti(n,x)48Sc reaction, it can be observed visually from Fig. 8 that our experimental result at the neutron energy of about 14.0 MeV is consistent with those of the previous experimental data from Mannhart and Schmidt (2007), Yuan et al. (1992) and Thiep et al. (2003) within the experimental error. The experimental value of Bovisio de Ricabarra et al. (1993) is significantly higher than those of others while the experimental value of Meadows et al. (1987) is significantly smaller than those of others at the corresponding energy.
Cross sections for the neutrons around 14 MeV interaction with natural titanium were precisely measured by neutron activation and off-line measurement technique. The fast neutrons were produced by ³H(d,n)⁴He reaction and the neutron energy was obtained by using the cross section ratio method of ⁹⁰Zr(n,2n)⁸⁹Zr to ⁹³Nb(n,2n)^92mNb reactions. Experimental cross sections have been acquired for ^natTi(n,x)⁴⁶Sc, ^natTi(n,x)⁴⁷Sc, ⁵⁰Ti(n,x)⁴⁷Ca and ⁴⁸Ti(n,x)⁴⁸Sc reactions. The measured cross section data are compared with the experimental data available in the previous literature and evaluated nuclear data from the ENDF/B-VIII.0, JEFF-3.3, JENDL-5, BROND-3.1, CENDL-3.2 and FENDL-3.2b libraries. Furthermore, excitation functions for these reactions were calculated by using the theoretical model based on Talys-1.96 code with default and adjusted parameters. Within experimental error, evaluated nuclear data are mostly consistent with experimental data. The excitation function with adjusted parameters can roughly reproduce the experimental data.
Application of Kalman filtering technique for evaluation of neutron cross section data of 100Mo (n, 2n) 99Mo reaction
2021, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
In this paper, for the first time, evaluation of neutron cross section data of ¹⁰⁰Mo (n, 2n) ⁹⁹Mo reaction is performed using experimental data available in IAEA-EXFOR database library and nuclear model-based data generated using Talys 1.9 code by applying a novel method of combining Kalman filtering technique with Machine Learning (ML) regression algorithms. The neutron cross section data evaluation has been performed after a detailed study of all the EXFOR papers corresponding to ¹⁰⁰Mo (n, 2n) ⁹⁹Mo reaction and nuclear model based cross section generation by executing T6 random input files using Talys 1.9 code. The evaluated curve generated is then compared with the existing evaluated curve of ¹⁰⁰Mo (n, 2n) ⁹⁹Mo reaction from nuclear data libraries such as ENDF/B-VIII.0, JEFF-3.3, JENDL-4.0, CENDL-3.1 and TENDL 2017 and found to be in good agreement with them. Chi-square and generalized Chi-square tests were employed to assess the proposed evaluation techniques and found them to be good in estimating evaluated mean values and evaluated uncertainties of cross section.
Investigating the excitation functions of the neutron-induced reactions leading to the radioactive products on natural titanium isotopes

According to the statistical analysis of this reaction, the best agreement with the experimental values [44,51,52,71,72,108,110,113,114] is the obtained excitation function using the BSFGM (Table 2). The theoretical excitation functions of the 50Ti(n,p)50Sc reaction and their comparison with experimental data and ENDF/B-VIII data [42,44,51,52,60,67,71,72,77,79,91,95,108,110,115–123] are presented in Fig. 6. After ⁓9 MeV the incident neutron energy, the nuclear level density models on the cross-sections are dominant.
In this study, the excitation functions of some (n, x) reactions leading to the radioisotope products on natural titanium isotopes, which is an important material for fusion technology, are calculated by using the ALICE/ASH and TALYS 1.95 codes. Besides, the effects of the phenomenological and the microscopic nuclear level density models on these excitation functions are investigated by using the two-component exciton and geometry dependent hybrid models. The obtained results for the considered reactions in this study are compared with the available experimental and ENDF/B-VIII data, and the suitable nuclear level density model is determined for each reaction. According to the results, the phenomenological nuclear level density models are generally in good agreement with experimental data, except for ⁴⁸Ti(n,d) and ⁵⁰Ti(n,γ) reactions. Also, the results of this study can be used to predetermine radiotoxicity in the structural material for a fusion reactor.
Measurements of formation cross-sections of short-lived nuclei around the 14 MeV neutron induced reactions on 180Hf and 90Zr and theoretical calculation of excitation functions
2021, Applied Radiation and Isotopes
The cross sections of the ¹⁸⁰Hf(n,p)¹⁸⁰Lu and ⁹⁰Zr(n,2n)^89mZr reactions were measured around the neutron energies of 13.5–14.8 MeV by using the activation technique. The excitation functions of the above reactions in the neutron energies from the threshold to 20 MeV were calculated by using the nuclear theoretical model program system Talys-1.9 with the adjusted relevant parameters. The measured results were discussed and compared with previous experiments by other researchers and with the evaluated data of ENDF/B-VIII.0, CENDL-3.1, JEFF-3.3, JENDL-4.0u2, BROND-3.1 as well as the theoretical values based on Talys-1.9. The obtained experimental values at some neutron energies, within experimental error, are consistent with those of the fitting line of the results of previous experiments and are also consistent with those of theoretical excitation curve at the corresponding energies. The obtained theoretical excitation curves match well with most of the experimental data.
Newly Evaluated Neutron Reaction Data on Chromium Isotopes
2021, Nuclear Data Sheets
Neutron reaction data for the set of major chromium isotopes were reevaluated from the thermal energy range up to 20 MeV. In the low energy region, updates to the thermal values together with an improved R-matrix analysis of the resonance parameters characterizing the cluster of large s-wave resonances for ^50,53Cr isotopes were performed. In the intermediate and high energy range up to 20 MeV, the evaluation methodology used statistical nuclear reaction models implemented in the EMPIRE code within the Hauser-Feshbach framework to evaluate the reaction cross sections and angular distributions. Exceptionally, experimental data were used to evaluate relevant cross sections above the resonance region up to 5 MeV in the major 52Cr isotope. Evaluations were benchmarked with Monte Carlo simulations of a small suite of critical assemblies highly sensitive to Chromium data, and with the Oktavian shielding benchmark to judge deep penetration performance with a 14-MeV D-T neutron source. A significant improvement in performance is demonstrated compared to existing evaluations.
