Abstract
Abstract In this study, the isomeric yield ratio (IR) values of 196m,gAu and 195m,gHg in the 197Au(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 γ-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 196m,gAu and 195m,gHg in the 197Au(p,x) reaction from the present and other works are compared with the similar literature data in the 197Au(γ,n), 196Hg(γ,n), 197Au(n,2n), 196Hg(n,2n), natPt(α,x) and natPt(3He,x) reactions to examine the role of compound nucleus spin, excitation energy, and input angular momentum.
