Investigation of isomeric ratios in (γ, n) reactions on rubidium isotopes in giant dipole resonance energy region

Abstract

Dependence on gamma-quanta energy of isomeric yield ratios obtained in 85Rb(γ, n)84m,gRb and 87Rb(γ, n)86m,gRb reactions within 10 - 18 MeV energy range have been studied. Thresholds of isomeric states excitations and energies of activation levels have been determined. Experimental results are compared with TALYS-1.0 calculations in the framework of statistical model
