Nilsson diagrams for light neutron-rich nuclei with weakly-bound neutrons
(2007) In Physical Review C: covering nuclear physics 76.- Abstract
- Using Woods-Saxon potentials and the eigenphase formalism for one-particle resonances, one-particle bound and resonant levels for neutrons as a function of quadrupole deformation are presented, which are supposed to be useful for the interpretation of spectroscopic properties of some light neutron-rich nuclei with weakly bound neutrons. Compared with Nilsson diagrams in textbooks that are constructed using modified oscillator potentials, we point out a systematic change of the shell structure in connection with both weakly bound and resonant one-particle levels related to small orbital angular momenta . Then, it is seen that weakly bound neutrons in nuclei such as 15-19C and 33-37Mg may prefer being deformed as a result of the Jahn-Teller... (More)

Then, it is seen that weakly bound neutrons in nuclei such as 15-19C and 33-37Mg may prefer being deformed as a result of the Jahn-Teller effect, due to the near degeneracy of the 1d5/2-2s1/2 levels and the 1f7/2-2p3/2 levels in the spherical potential, respectively. Furthermore, the absence of some one-particle resonant levels compared with the Nilsson diagrams in textbooks is illustrated. (Less)
