Pair correlation in neutron drip line nuclei
(2003) In Physical Review C (Nuclear Physics) 68(3: 034312). Abstract
 The HartreeFockBogoliubov (HFB) equation in a simplified model is solved in coordinate space with the correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line. The occupation probability obtained in the HFB approach for lowerl orbits decreases considerably already when the binding energy of the corresponding HartreeFock (HF) oneparticle level becomes smaller. When the HF oneparticle level enters into the continuum, the lowerl orbit soon becomes almost unavailable for the pair correlation of the manybody system. In contrast, the contribution to the pair correlation by highl orbits which have oneparticle resonant levels with narrow width in the HF potential can be... (More)
 The HartreeFockBogoliubov (HFB) equation in a simplified model is solved in coordinate space with the correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line.

When the HF oneparticle level enters into the continuum, the lowerl orbit soon becomes almost unavailable for the pair correlation of the manybody system. In contrast, the contribution to the pair correlation by highl orbits which have oneparticle resonant levels with narrow width in the HF potential can be estimated in the BCS approximation using the oneparticle resonant energies, though the associated wave functions in the HFB approach are boundstate wave functions.
