Band crossing and the N=7 intruder orbital in superdeformed nucleus 193Hg Original Research Article

The particle-number conserving method for treating the cranked shell model with monopole and quadrupole pairing interactions is used to investigate the microscopic mechanism of six superdeformed bands in 193Hg, including the occupation probability of each cranked orbital, the contributions to angular momentum alignment from the direct contributions jx(μ) of the particle in orbital μ, and the interference contribution jx(μν) from the particles in orbitals μ and ν. Our calculated results support the previous assignments of configuration of six superdeformed bands in 193Hg and provide a satisfactory demonstration for the crucial role of the high-N intruder orbital ν[761]3/2 in band crossing and angular momentum alignment.
