Abstract

Examples of phase transitions occurring in atomic nuclei in response to an increase in the excitation energy and angular momenta and in response to a change in the number of nucleons are considered. The possibility of describing such transitions within collective models based on a Hamiltonian that depends on a relatively small number of dynamical variables is demonstrated.

原子核的相变和形状共存

摘要

考虑了响应于激发能量和角动量的增加以及响应于核子数量的改变而在原子核中发生的相变的示例。证明了在基于相对较少数量的动态变量的哈密顿量的集体模型内描述这种转变的可能性。
