Measurement of the isomeric yield ratios of 196m,gAu and 195m,gHg in the 197Au(p,x) reaction

초록

In this study, the isomeric yield ratio (IR) values of Au-196m,Au-g and Hg-195m,Hg-g in the Au-197(p,x) reaction within the proton energy range of 49.8-65.5 MeV were measured at the high-intensity proton linac facility (KOMAC) in Korea using an offline ?-ray spectrometric technique. Furthermore, the IR values of the above-mentioned products at different proton energies were calculated from the cross-sections based on the data in the TENDL-2019 library and are found to be higher than the experimental values. The IR values of Au-196m,Au-g and Hg-195m,Hg-g in the Au-197(p,x) reaction from the present and other works are compared with the similar literature data in the Au-197(?,n), Hg-196(?,n), Au-197(n,2n), Hg-196(n,2n), Pt-nat(a,x) and Pt-nat(He-3,x) reactions to examine the role of compound nucleus spin, excitation energy, and input angular momentum.
