Abstract

Some results obtained by E.E. Saperstein and his coauthors in the theory of the ground state and low-lying excited states of magic and semimagic nuclei are discussed briefly. Corrections to the creation amplitude \(g\) for one low-lying phonon are considered for the first time. These corrections, treated on the basis of the existence of a small parameter, include the tadpole-induced coupling of the amplitudes for the creation of one and two phonons.

有限费米系统理论中的非谐效应

摘要

简要讨论了EE Saperstein及其合著者在魔术和半魔术核的基态和低位激发态理论中获得的一些结果。首次考虑对一个低位声子的产生振幅\（g \）进行校正。这些校正是在存在一个小参数的基础上进行的，其中包括-引起的振幅耦合，以产生一个和两个声子。
