摘要：
Continuum effects in the weakly bound nuclei close to the drip line are investigated using the analytically soluble Poschl-Teller-Ginocchio potential. Pairing correlations are studied within the Hartree-Fock-Bogoliubov method. We show that both resonant and nonresonant continuum phase space is active in creating the pairing held. The influence of positive-energy phase space is quantified in terms of localizations of states within the nuclear volume, [S0556-2813(99)02209-8].
