Development of (p,p′γ) detection capabilities at iThemba LABS through the study of low-lying E1 strength in 58Ni

Abstract

Abstract This work is a feasibility study designed to test and develop the (p,p′γ) detection capabilities at iThemba LABS when the K600 magnetic spectrometer at 0° is coupled to an array of high purity germanium and cerium-doped lanthanum bromide detectors. This is done through an investigation into the low-lying E1 strength of 58Ni with a proton beam of E p = 80 MeV. The coincidence matrix of the energies of the excited states and the subsequent γ decays is presented and decays to the first excited state and ground state were identified. The results of this study are compared with previous (α, α′γ) studies.
