Abstract: Neutron induced reaction cross-sections of the isotopes 52Cr, 53Cr, 90Zr, 91Zr, 92Zr, 94Zr, 116Sn, 118Sn and 120Sn for (n,p), (n,n’), (n,a) and (n, 2n) reactions have been evaluated at 14 MeV. The computations are based on the evaporation model considering the pre-equilibrium emission mechanism under some approximations. The computer codes ALICE-91, NX-1 and SC2N3N have been used. These cross-sections were also computed using the level density formula of Lang and Le Couteur with and without applying pairing energy correction. The compound nucleus theory based on Fermi gas and evaporation model with optical model potential parameters has been used. The neutron, proton and alpha penetrabilities and inverse reaction cross-sections have been computed using the computer code SCAT-2. The computed cross-sections have been compared with the available experimental values and the results are in fairly good agreement.
