Results From Capture Reaction Measurements on Sn and Pd for the γ-Process Using HECTOR

ORAL

Abstract

The formation of p-nuclei and their abundances are an important and ongoing study in nuclear astrophysical measurements. To understand and constrain theoretical models on the abundances of p-nuclei, further measurements of important branching points of the γ-process are needed. To constrain the 120Te(γ,α)116Sn reaction rate, the cross sections of (p,γ) and (α,γ) reactions on 112,114,116Sn and 108Pd(p,γ)109Ag were investigated over a combined energy range of Ep=2.5-7 MeV and Eα=10.5-14 MeV, for protons and alpha particles, respectively. These measurements were performed utilizing the γ-summing detector HECTOR and the FN accelerator at the Nuclear Science Laboratory at the University of Notre Dame. In this talk, results for these various reactions will be presented.
