Effective pairgap of weaklybound neutrons in deformed nuclei
(2005) In Physical Review C (Nuclear Physics) 71(3). Abstract
 The dependence of effective pair gap on weakly bound neutron orbits is studied in deformed nuclei in comparison with that in spherical nuclei, solving the HartreeFockBogoliubov equation in a simplified model in coordinate space with the correct asymptotic boundary conditions. In spherical nuclei the effective pair gap of s1/2 neutrons decreases to zero in the limit that the corresponding HartreeFock oneparticle energy approaches zero. In the same limit, the effective pair gap of =1/2+ neutrons in deformed nuclei becomes very small when the wave functions of =1/2+ orbits contain an appreciable amount of s1/2 components, even if a considerable amount of largercomponents remains in the wave functions. Then, the oneparticle excitation... (More)

Then, the oneparticle excitation spectra of deformed eveneven neutrondripline nuclei, in which an =1/2+ level is weakly bound, can start at much lower energy than twice the average pair gap in the presence of manybody pair correlation.
