摘要：

We show that the linear energy weighted M 1 sum rule is proportional to the summed E 2 strength in the region of vibrational, transitional, and strongly deformed even-even nuclei using the proton-neutron interacting boson model. This general relation is compared with extensive data on M 1 and E 2 transition strength in rare-earth nuclei truncating the M 1 sum rule to states below an excitation energy of 4 MeV. The above observation also implies a quadratic dependence on deformation (delta) for the summed orbital M 1 strength.
