Abstract
The possibility of the investigation of the low energy portion of the neutron spectra in reflecting fast reactors by activated resonance detectors is considered.
Absorber difference and “1/v absorption” methods are illustrated by an example of the measurement of the flux distribution of resonance neutrons with energies of 4.9 ev (Au197) and 2.95 kev (Na23) in the reflecting reactors BR-1 and BR-5. It is shown that the neutron spectrum region from one to several thousand electron volts can be studied in adequate detail with the aid of the set of detectors described.
