The low-lying M1 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.
