Abstract

Differential cross sections for gamma-ray emission from the 107Ag (p, p′γ3-0)107Ag and 109Ag (p, p′γ3-0)109Ag reactions in the proton energy range 1200–2700 keV were measured at 90⁰ in the laboratory frame. In addition, differential cross sections for gamma-ray emission from the 107Ag(p, p′γ4-0)107Ag and 109Ag(p,p′γ4-0)109Ag reactions in the proton energy range 1310–2700 keV and 1330–2700 keV in the mentioned condition. The measurements were performed using the proton beam of the 3 MV Van de Graaff electrostatic accelerator of Nuclear Science and Technology Research Institute (NSTRI) in Tehran. Besides, the validity of the measured differential cross sections was verified through comparison between calculated thick target yields deduced from present work excitation curve and experimental thick target yield data available from literature. The overall systematic uncertainty of the measured values was estimated to be less than 8%.
