Proton strength functions of64Zn and66Zn

Abstract
A high-resolution study of the (p,p) reaction has been performed on 64Zn and 66Zn in the energy ranges Ep=2.50-3.24 Mev and 2.60-3.26 MeV, respectively. Resonance parameters were obtained for 39 resonances in 65Ga and for 148 resonances in 67Ga. The proton strength function was determined to be S0=0.051+or-0.013 for 64Zn and S0=0.078+or-0.016 for 66Zn. Spectroscopic properties were obtained for five isobaric analogue states, including the fine-structure parameters for two fragmented analogues in 67Ga.
