Abstract

Lifetimes of excited states in 68Cu were measured by the γ-γ-t coincidence using two BaF2 detectors through the decay of 68Cum produced by the (n,p) reaction. The half-life of the 2+ state at 84 keV was obtained as 7.84(8) ns, corresponding to the B(M1;2+ → 1+) value of 0.00777(8)μN2. A shell model calculation with a minimum model space of πp3/2νp1/2-1 gives a good prediction of this B(M1) value by using experimental g factors of neighboring nuclei. This small B(M1) value can also be explained by a shell model calculation in the f7/2-r(p3/2f 5/2p1/2)n+r(r=0,1) model space.
