Influence of reaction channel on the isomeric cross-section ratio

The influence of reaction channel on the isomeric cross-section ratio was investigated by analysing the experimental data on the reactions ⁵²Cr(p,n)^52m,gMn, ⁵²Cr( ³He,t)^52m,gMn, ⁵⁴Fe(d,α)^52m,gMn, ⁵⁴Fe(n,t)^52m,gMn and ⁵⁴Fe( ³He,α p)^52m,gMn over the incident particle energy range extending up to 35 MeV. The influence is most pronounced when the channels differ widely, for example (p,n) and ( ³He,t) processes, i.e. when the reaction mechanisms are different. The nuclear model calculational code EMPIRE-II described the isomeric cross-section ratio rather well in the case of a simple nucleon emission reaction, but not when complex reaction channels were involved.
