| 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. |
