چکیده انگلیسی
The isomeric cross section of 137Ba(n, nâ²)137mBa reaction over the neutron energy from 1 keV to 4 MeV has been calculated using TALYS-1.2 nuclear code. The variations of cross section with level densities and effective imaginary potentials have been studied to obtain the best fit with the excitation function. The reaction cross section for Barium was also measured in continuous neutron energy using the Microtron accelerator based neutron source. In this case, the bremsstrahlung radiation emitted by impinging 6 MeV electrons on the e-γ primary target (tungsten) was allowed to fall on the γ-n secondary target (beryllium) to produce continuous neutrons and further barium was irradiated at 00 with respect to the incoming neutrons. It is observed that the experimental cross section for Barium is in good agreement with TALYS code and also evaluated data of EXFOR. Deviation factor has been determined for measuring and theoretical cross sections by TALYS-1.2 found to be around 14.71.
