Se(p,γ) cross section measurements for p-process studies Original Research Article

As a continuation of a systematic study of reactions relevant to astrophysical p-process, the (p,γ) or (p,n) cross sections of three Se isotopes have been measured using an activation technique in the proton energy range between 1.3 and 3.6 MeV. The resulting cross sections of the 74,76Se(p,γ)75,77Br and 82Se(p,n)82Br reaction have been compared with the predictions of Hauser-Feshbach statistical model calculations using the NON-SMOKER and MOST codes. In all three cases the theory is in satisfactory agreement with the measurements.
