摘要：

A consistent analysis of E2 transition probabilities for nine neutron-deficient even-even Se, Kr, and Sr isotopes has been performed, based on previous parametrizations for these nuclei within the proton-neutron interacting-boson model, from which boson effective charges e and e are deduced. Two sets of effective charges are obtained, one set having ee for most of the nuclei studied, and the other set having e substantially larger than e for most of the nuclei. For both sets, e tends to decrease with increasing neutron number, while e is roughly constant. More information on mixed-symmetry states is needed to determine which set is valid. © 1990 The American Physical Society.
