Abstract
The dependence of isomeric yield ratios upon the maximum bremsstrahlung gamma-quanta energy for the 120Te(γ, n)119m,gTe and 122Te(γ, n)121m,gTe reactions within an energy range of the giant dipole resonance is investigated. Cross-sections of excitation of metastable states with J π = 11/2− of the 119Te and 121Te nuclei are obtained. Experimental data are compared with computation results obtained using the TALYS-1.2 software package.
