Excitation functions of the 197Au(p,pxn) and 197Au(p,xn) reactions

The cross-sections for the Au-197(p,pxn)Au196-193 and Au-197(p,xn)Hg-197,Hg-195,Hg-193 reactions within the proton energy range of 49.8-65.5 MeV were measured at the high-intensity proton linac facility (KOMAC) in Korea using the stacked-foil activation and off-line ?-ray spectrometric technique The proton beam intensity was determined based on the Cu-nat(p,x)Zn-62 monitor reaction with the recommended cross-section accessed from the IAEA database library. The data gathered in the present work are compared with the available data from the literature, which agreed well with each other. In this study, the Au-197(p,p5n)Au-193 reaction cross-section was measured for the first time. The data from the present work and existing literature were compared with the TALYS-1.9-based data taken from the TENDL-2019 library, which generally agreed well.
