Measurement of isomeric yield ratios for 104m,gAg and 106m,gAg isotopes using bremsstrahlung end-point energies of 45-75 MeV

초록

In this study, the isomeric yield ratio (IR) values of 104(m,g)Ag and 106(m,g)Ag in an Ag-nat(gamma,xn) reaction at the bremsstrahlung end-point energies (Ee) of 45, 50, 55, 60, 70, and 75 MeV were measured using an off-line gamma-ray spectrometric technique. The IR values at different bremsstrahlung end-point energies were also calculated from the cross-section data available in the TENDL-2019 library, and they were found to exhibit a similar trend with some differences in the magnitude. Herein, the IR values of Ag-104m,Ag-g and 106(m,g)Ag with the bremsstrahlung end-point energies of 70 and 75 MeV were measured for the first time. The present data were compared with those from the literature for Ag-107,Ag-109,Ag-nat(gamma,xn), Ag-nat(n,xn), Pd-nat(p,xn), and 103Rh(alpha,xn) reactions to examine the role of the excitation energy and input angular momentum.
