The Ground State Occupation Probabilities Of Valence Nucleon Pairs With Various Angular Momentum Quantum Numbers For Even-Even Nuclei In The Nilsson Mean-field Plus Nearest-Orbit Pairing Model

Concent:The binding energies and even—odd nlaS8 differences of light nuclide(20-28)~Ne,(22-30)~Mg and rare-earth regions (160-166)~Er are calculated by applying the exactly solvable mean-filed plus nearest-orbit pairing model for the description of well-deformed nuclei. Comparedwith the corresponding experimental values,the results of binding-energies and even-odd massdifferences are basically obtained. Furthermore,the valence nucleon pairs occupation number oflight nuclide even-even nucleus(20-28)~Ne,(22-30)~Mg and rare-earth even-even nuclide (160-166)~Er arecomputed. As an approximation,pairing interaction between protons and neutrons is ignored.It is inferred that the probabilities of even angular momenta are nmch higher than those of oddangular momenta. So S,D,G bosons make great contributions to the ground wave functions.
