Abstract
摘要 提出了一种从理论上检验壳效应的方法.在考虑了由Bardeen，Cooper和Schrieffer提出的金属超导理论(BCS方法)的相对论平均场理论框架内，通过计算粒子数的涨落，发现涨落的大小和核的壳结构有紧密的关系，进而研究了滴线区一些传统幻数的消失和新幻数的产生. 关键词: 相对论平均场理论 / 粒子数涨落 / 幻数 / 壳效应 Abstract A theoretical method which is applied to examine the shell effects is presented. Namely， by calculating the particle number fluctuation in the framework of the relativistic mean-field model including BCS method，we find that the size of the particle number fluctuation is related to the nuclear shell structure. Based on this method， the disappearance of conventional magic numbers and the presence of new magic numbers near drip-line region are studied.
