Abstract
The cross sections of 127I(n, γ)128I, 23Na(n, γ)24Na and 51V(n, γ)52V reactions for Iodine, sodium and vanadium were measured at continuous energy spectrum using a Microtron accelerator based neutron source. In this case, the bremsstrahlung radiation emitted by impinging 6MeV electrons on the e–γ primary target (tungsten) was allowed to fall on the γ–n secondary target (beryllium) to produce continuous neutrons. The optimization of bremsstrahlung and neutron producing targets along with their spectra were estimated using FLUKA code. The cross sections of 127I(n, γ)128I, 23Na(n, γ)24Na and 51V(n, γ)52V reactions over the neutron energy from 1keV to 4MeV have been also calculated using the TALYS-1.2 and EMPIRE nuclear model codes. The variations of the cross sections with the level densities and effective imaginary potentials were studied to obtain the best fit of the excitation function. It is observed that the experimental cross sections for iodine, sodium and vanadium are in good agreement with the TALYS-1.2 and EMPIRE codes.
