Description
A model interpretation of isomeric ratios for 117m,gIn and 120m,gSb produced in the reactions 118Sn(γ,p), 119Sn(γ,np), 121Sb(γ,α), natSb(γ,α2n), 121Sb(γ,n) and natSb(γ,3n) is presented. The experimental isomeric ratios were obtained using bremsstrahlung radiation with end-point energies of 18 and 43 MeV. The calculations were performed by means of the well known code STAPRE and the new code COMPLET. Angular-momentum removal in pre-equilibrium emission was found to be much more important for the observed isomeric ratios than subsequent compound-nucleus evaporation. (author)
