Abstract

The method of induced activity of the investigated cross-sections of excitation of isomeric states in the 110Pd(y,n)109m,gPd and 110Pd(n,2n)109m,gPd reactions in the energy range 12–35 MeV is studied. The experimental results are compared with those of calculations carried out using the software package TALYS-1.6.
