The gamma decay of analogue states in61Cu

  • Published:
Zeitschrift für Physik

Abstract

Resonances in the reaction60Ni(p, γ)61Cu have been studied in the proton energy rangesE p=1840–1880 keV and 2220–2300 keV. Decay schemes and branching ratios have been determined for a number of resonances, three of which are identified as analogue fragments of the 283 keV (1/2−) and 656 keV (3/2−) states in61Ni. The split analogue components of the 283 keV state atE x≈6.6 MeV are seen to decay significantly to a group of states in the region of excitation 3–4 MeV. Gamma ray angular distributions yield the following resonance spins:E p=2248 keV,J=3/2;E p=2263 keV,J=5/2. Also, the61Cu ground stateβ + decay to parent levels in61Ni has been compared to the respective analogue stateM1 gamma decay to the61Cu ground state.
