Resonances in the reaction 56Fe(p, γ) 57Co

Abstract

Resonances in the reaction 56Fe(p, γ) 57Co have been surveyed over the energy range 1.2 ⪅ E p ⪅ 1.5 MeV wherein the analogues of the ground state (J π = 1 2 −, 0.014 MeV state (J π = 3 2 −) and 0.136 MeV state (J π = 5 2 −) of 57Fe are expected to occur. Gamma-ray angular distributions have been used to establish resonance and bound-state spins, and decay schemes have been determined. The analogue resonances appear to be severely fragmented, however the density of resonances of a given spin correlates quite well with ( 3He, d) results and with the expected analogue-state positions.
