Neutron cross-sections for 55Mn in the energy range from 0.2 to 22 MeV

Neutron total and differential elastic scattering cross-sections for 55Mn nucleus was calculated from different global spherical optical potential (SOP) sets for different neutron energies ranging from 0.2 MeV to 22 MeV using the well known computer program SCAT-2 on an IBM PC-AT. In addition, the angular distributions of elastically scattered neutrons at different neutron energies were calculated. The results were compared with those of the experimental data obtained from the EXFOR data file of NEA data bank. The best-fit potential parameter was thereby selected. It was observed that the best fit to the experimental values of the total cross-sections are obtained by SOP parameters of Kawai for 55Mn. Furthermore, the variations of the total cross-sections as a function of real potential depth V0 and real radius parameter r0 were calculated to observe the sensitivity of these parameters towards the cross-sections
