摘要
本文介绍并发展了一种从实验结合能及激发能提取质子-中子互作用能δV_(pn)的方法,据此对N≥40全部偶偶核的基态及部份核的高自旋态的质子-中子互作用作了讨论。同时,还讨论了一些奇A核中特定组态的高自旋态的质子-中子互作用。结果表明,这类实验δV_(pn)值包含着p-n互作用的各种多极项,主要是单极和四极项,而且灵敏地依赖于核的形变,组态与转动频率。
A method for extracting the empirical proton-neutron interaction energy between the last proton and the last neutron, σV_(pn) has been discribed and developed. The results for ground states of all even-even nuclei with N not less than 40 and for high spin states of some nuclei have been discussed. σV_(pπ) values at high frequency for given configuration of some odd A nuclei were shown as well. It is found that these empirical σV_(pn) values include all multipole (mostly the monopole and quadrupole) terms of proton-neutron interaction and sensitively depend on nuclear deformation, configuration and rotational frequency.
