Measurement of excitation functions and analysis of isomeric population in some reactions induced by proton on natural indium at low energy

The excitation functions for reaction residues populated via In115(p,p)115mIn, In115(p,pn)114mIn, In115(p,p2n)113mIn, In113(p,p)113mIn, In115(p,nα)111mCd, In115(p,3n)113Sn and In113(p,n)113Sn channels were measured over the proton energy range of 8-22 MeV using stacked foil activation technique. Theoretical analysis of the data were performed within the framework of two statistical model codes EMPIRE-3.2 and TALYS-1.8. Isomeric cross section ratio for isomeric pairs Inm,g115, Inm,g114, Inm,g113, S113nm,g and Cdm,g111 were determined for the first time. The dependence of isomeric cross section ratio on various factors are analysed.
