Effect of weakly-bound neutrons on pair-correlation and deformation

• The unique role of weakly-bound low-angular-momentum neutrons in the structure of neutron-drip-line nuclei is presented, studying both the many-body pair-correlation in spherical nuclei and the one-particle orbits in the deformed Woods-Saxon potential. Both the HFB equations in the former case and the Schrodinger equation in the latter are solved in coordinate space with correct asymptotic boundary conditions. Combining the results of those two cases, it is concluded, for example, that all Ωx=1/2+ one-particle levels become practically unavailable for both deformation and many-body pair-correlation, when the HF one-particle levels approach continuum or lie in the continuum
