在自洽的相对论平均场理论框架下,用严格保持粒子数守恒的类壳模型方法,即RMF+SLAP方法,研究了Sn周位素链的性质并与没有考虑对关联对平均势场影响的非自洽计算进行了比较．结果表明,自洽的RMF+SLAP方法能够正确给出原子核形变随平均对力强度的变化,给出Sn同位素链的每核子结合能,单中子与双中子分离能,四极形变随质量数A的变化等的很好描述．表明了研究原子核性质时,正确和自洽处理对关联以及堵塞效应的重要性． Under the framework of the self-consistent relativistic mean-field theory, the properties of the Sn-peridotin chain are studied by using the shell-like-model method that strictly preserves the conservation of particle number, that is, the RMF + SLAP method. Compared with those without considering the influence on the average potential field Calculations have been compared. The results show that the self-consistent RMF + SLAP method can correctly give the change of nuclear deformation with the average force against each other, and give the energy per nucleon of the Sn isotope chain. The separation energies of single and double neutron, A number of changes such as a good description. Shows the importance of correct and self-consistent handling of association and plugging effects when studying the nature of nuclei.
