Abstract

M1 and E2 transition probabilities from the K=1 band, which is lowestin energy among the mixed-symmetry bands, to fully symmetric states are derived analytically within the framework of the SU(3) limit of theneutron-proton interacting boson model. To derive the electromagnetictransitions in closed forms, the tensorial characters of the electromagnetic transition operators, which are taken in terms of SU(3) generators, are investigated in the pure SU(3) limit. The properties of M1 and E2 intrinsic matrix elements in the classical limit of the present model and the E2/M 1 mixing ratios for transitions of the K=1 band to fully symmetric states are also studied.
