MICROSCOPIC THEORY OF NUCLEAR COLLECTIVE ROTATION .2. MICROSCOPIC DESCRIPTION OF DEFORMED-NUCLEI

For pt.I see ibid., vol.5, no.3, p.341 (1979). A unified treatment of collective rotation and internal motion in deformed nuclei is outlined. The description of internal motion by intrinsic wavefunctions, given in body-fixed particle coordinates, leads to the so called intrinsic Hamiltonian which depends on the definition of the body-fixed frame. The eigensolutions of this operator prove to be deformed. To determine these intrinsic wavefunctions, a doubly self-consistent problem has to be solved. If the HFB method is used, this means that the best possible reference frame in which the internal motion is described approximately by independent quasiparticles is determined (by specific decoupling).
