摘要
An earlier coexistence model of Ge nuclei is applied to E2 strengths connecting low-lying 0(+) and 2(+) states in Ge-72. New data have smaller uncertainties and, for the first time, a value for the transition strength from the third 2(+) state to the second 0(+) state. This B(E2) for the third 2(+) state clearly indicates that it is the one that should be included in the mixing, rather than the second 2(+) state. My results confirm that the 0(+) states are maximally mixed, the 2(+) states are weakly mixed, and the E2 matrix element involving the lower 0(+) basis state is significantly larger than the one involving the second 0(+) basis state.
