Abstract
Abstract Within the framework of the Interacting Boson Model (IBM), we discuss rotational damping, which has a close relation to the transition from order to chaos at high-spin states. We discuss the basic mechanism of its appearance by showing the average and fluctuation properties of the level density and electromagnetic transitions, in the system governed by the quadrupole-quadrupole interaction at highly excited, high-spin states. It is demonstrated that an unexpected regularity arises at high-spin states due to quadrupole-quadrupole interaction. We present an articulate elucidation on the importance of the higher multipole interactions, which cause the mixing among highly excited rotational bands. For the damping width of the rotational bands, an explanation based on the SU(3) limit of the IBM is suggested.
