混合组态壳模型计算氧同位素能谱

本文用新修正表面δ力(NMSDI)作为有效相互作用,在1d5/2-1d3/2空间计算了A=17-22的氧同位素的能级。为了进行比较还用了修正表面δ力作为有效相互作用(MSDI)进行了计算。计算的能量矩阵元都是五个可调参数,与实验比较:(NMSDI)的结果比较好;核表面附近的核子间的剩余相互作用确是主要的,核内核子间的剩余相互作用力也是存在的,它作为表面相剩余互作用的一项修正更有意义。本工作还与其他作者的工作进行了比较,无论在能级次序上,还是在和实验能级符合数目上都得到比较好的结果。本工作用的参数少,而符合的能级数多。

MIXED-CONFIGURATION SHELL-MODLE CALCULAIIONS FOR SPECTRA OF~(17-22)O

Euergy Levels of~(17-22)O have been calulated with the use of The New Modified Surface Delta Interaction(NMSDI) and the Modified Surface Delta Interaction (MSDI)as residual interaction. Either of two residual interactions have five parameters, The results show that the NMSDI is better agreement with experiment than the MSDI. The prevalence which is obtained from comparing this work with the others is the paramters less and agreement with energy levels more,
