Abstract

The isomeric cross-section ratios are calculated for the reactions ¹¹³,In(a,n)¹¹⁶Sb^m,g, ¹¹⁵In(,3n)¹¹⁶Sb^m,g, ¹¹⁶Sn(p,n)¹¹⁶Sb^m,g, ¹¹⁶Sn(d,2n)¹¹⁶Sb^m,g, ¹¹⁷Sn(p,2n)¹¹⁶Sb^m,g, ¹¹⁵In(,n)¹¹⁸Sb^m,g, ¹¹⁶Sn(,pn)¹¹⁸Sb^m,g, ¹¹⁸Sn(p,n)¹¹⁸Sb^m,g ¹¹⁸Sn(d,2n)¹¹⁸Sb^m,g, ¹¹⁹Sn(p,2n)¹¹⁸Sb^m,g, ¹¹⁷Sn(n,p)¹¹⁷In^m,g, ¹¹⁸Sn(p,a)¹¹⁵Inm,g over the energy ranges from threshold up to 40 MeV using the nuclear reaction code EMPIRE 3.1. It is found that isomeric cross-section ratio depends on the spins of ground and isomeric states of residual nucleus as well as the incident energy. The isomeric cross-section ratio increases slowly for the cases where larger angular momentum ( ΔJ) is carried away by the emitted particle and increases sharply when ΔJ is smaller.
