摘要：

We discuss the systematics of E2 and M1 transition strengths as obtained from experimental data in the rare-earth region. The similarity is studied in the light of the observed dependence of E2 and MI transition strength on quadrupole deformation. Especially the "saturation" effect for these electromagnetic observables is discussed, starting from the Nilsson deformed-shell model. The data are compared to the present calculations, using a QTDA approach. The particular E2-M1 correlation is investigated within the IBM-2 using a sum-rule approach.
