The low-lying [Formula Presented] transition strength distributions observed in rare earth and actinide nuclei reflects on both the collective and noncollective aspects of the nuclear interaction. As shown in this article, the pseudo-SU(3) model can accommodate these complementary features and provides a natural interpretation for different aspects of this “scissors” mode. © 2000 The American Physical Society.
