Abstract

The results of the analysis of the first four energy levels of the ground-state rotational bands of even-even nuclei from 6C8 to 56Ba90 on the basis of the revolving-cluster model are reported. Values of the nucleon number of the revolving cluster are assigned on the basis in part of the shell model and in part of the expectation that the corresponding values of the radius of revolution would change only slightly from one energy level to an adjacent level or from one nucleus to an adjacent nucleus. The values of the radius of revolution are found to change gradually from about 5 to 6 fm for the lighter nuclei to 7 to 8 fm for the heavier nuclei in the sequence studied.

摘要

报告了基于旋转集群模型对从(^{6}C^{8})到(^{56}Ba^{90})的偶偶核基态转动带前四个能级的分析结果。旋转集群的核子数取值部分基于壳模型，部分基于这样的预期：从一个能级到相邻能级，或从一个核到相邻核，相应的旋转半径值只会有轻微变化。在所研究的序列中，发现旋转半径值从轻核的约5飞米到6飞米逐渐变化到重核的7飞米到8飞米。
