Abstract

Two subjects related to nuclear rotation at low angular momentum are discussed. One is the γ-soft “rotation” in a microscopic calculation of the IBM-2, where it will be shown that we can reproduce γ-soft collective levels in a microscopic IBM-2 using a standard effective nucleon-nucleon Hamiltonian. The other is about the rotation of the axially-symmetric rotor. It is shown that, in and near the ground state, the proton and neutron deformed ellipsoids are rotating in the opposite directions, whereas they rotate about almost the same axis in states of higher spins. This holds, quite similarly, for angular-momentum-projected Nilsson wave functions and for wave functions in the Interacting Boson Model.
