摘要：
We study the relevance of nucleon pairs with higher spins, in addition to spin-zero and spin-two pairs (i.e., S D pairs), in low-lying states of even-even Xe nuclei. By including those higher-spin pairs in our configuration, we recalculate energy level schemes, electrical quadrupole moments, magnetic moments and electric quadrupole transition rates, for low-lying states of even-even Xe128-142 nuclei. The agreement between our calculated results and the experimental data is substantially improved in comparison with previous studies.
