Abstract

A systematic investigation was carried out on115In to determine the contribution of different reactions to the total non-elastic cross-section in the 13.43 and 14.84 MeV incident neutron energy range. All the major components of σNE were measured with exception of the σg(n, n′) cross section. An analytical expression is recommended to estimate the σNE data as a function of mass number at En=14.1 MeV. By the knowledge of σNE, the energy dependence of σg(n, n′) could be deduced. The isomeric cross section ratios both for (n, 2n) and (n, n′) processes were also determined in the given energy range. The present experiment proves the dependence of σm/(σgm) ratio on the spin value (Im) of the isomeric state in the (n, 2n) reaction. Excitation functions of the (n, 2n), (n, n′) (n, p) and (n: p, α) reactions calculated by STAPRE code show good agreement with the experimental results.
