STUDY OF THE EXCITATION OF ISOMER STATES IN THE REACTIONS (γ,n) AND (n,2n) SELEN ISOTOPES
Downloads
The excitation cross sections of isomeric states in reactions (γ,n) and (n,2n) on selenium isotopes in the energy range 11-35
MeV were studied using the induced activity method. The experimental results are compared with calculations carried out
using the TALYS-1.6 software package.
