Inelastic Electron Scattering Form Factors for 13_C with Core-Polarization Effects

Inelastic electron scattering have been calculated for the longitudinal and transverse form factors for ¹³C nuclei. The zero-order calculations are based on the model space-wave functions of Cohen-Kurath (ck) interaction first and on the Millener (mp) interaction second in the frame work of shell model. The single-particle wave functions are those of Harmonic Oscillator (HO). Core-polarization effects are used in these calculations, where a core (⁴He) is assumed and the remaining particles are distributed over of 1p _1/2 and d1p _3/2 Orbits which form the model space. The effect of core-polarization is found very essential by using (ck) interaction more than (mp) interaction, the calculated results gives a good description of the data with adjustable parameters. The results have been calculated for the states: (J^π = (1/2)^–, T = 1/2)8.86 MeV, ((5/2)^–, 1/2)5.77 MeV, ((3/2)^–, 1/2)3.68 MeV, and ((3/2)^–, 3/2)15.11 MeV.
