现代壳模型
Contemporary Nuclear Shell Models

摘要: 传统壳模型存在的一个主要问题是计算过于复杂以致无法进行.随着计算机计算能力的空前提高,现在已经可以进行极大规模的壳模型计算.然而,还不清楚这种计算对于深入理解物理问题是否有实际帮助.况且,对于组态空间可达1014—1018维的中重核,当前的计算机能力还达不到.因此对中重核仍需研究如何把巨大的模型空间截断到最佳的可操作子空间的问题.近来提出的配对壳模型给出了一个很有用的方法,其它截断模型可归入它的特殊情况.与此同时,从现实有效二体相互作用出发进行壳模型多体计算方面也正在取得巨大的进展. The current status on the theoretical investigations of the nuclear shell model is reviewed, and the fundamental problems in shellmodel studies are mentioned. Basically the shellmodel uses a very intuitive approach to study the nuclear manybody dynamics in terms of valence particles. It assumes that the nucleons, belonging to a closed core, do not participate in the establishment of the nuclear spectrum. One of the main problems in the (traditional) shell model is to make a calculation...Abstract: The current status on the theoretical investigations of the nuclear shell model is reviewed, and the fundamental problems in shellmodel studies are mentioned.
