The Perturbed Angular Correlations for the (596 – 42) keV Cascade in ⁶²Cu

Abstract

The ⁶²Cu nucleus has one proton and five neutrons outside the closed shells of Z, N = 28. The reported experimental value of the magnetic moment of the nucleus in the 1⁺ ground state is in fair agreement with theoretical predictions based on the Hamada — Johnston interaction potential, with which a very strong configuration mixing was obtained¹). Similarly, for the 2⁺ ground state of ⁶⁰Cu the agreement between the experimental and predicted values of the magnetic moment is quite satisfactory. As the low — lying first excited 2⁺ state of ⁶²Cu has the same spin and parity as the ground state of ⁶⁰Cu, it is interesting to measure its magnetic moment. The performed experiment includes directional correlation measurements on the (596-42) keV γ — γ cascade observed in the decay of ⁶²Zn.
