Pair correlation in deformed neutrondripline nuclei: The eigenphase formalism and asymptotic behavior
(2006) In Physical Review C (Nuclear Physics) 73(4). Abstract
 The HartreeFockBogoliubov (HFB) equation for deformed nuclei in a simplified model is solved in coordinate space with correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line. The eigenphase formalism is applied, when the upper components of HFB radial wave functions are continuum wave functions. Calculated occupation probabilities of various Nilsson orbits in the HFB ground state vary smoothly from the region of the upper components being bound wave functions to that of those being continuum wave functions. It is shown that weaklybound or resonancelike Omega(pi)=1/2(+) Nilsson orbits contribute little to the occupation probability of the HFB ground state, while the... (More)
