Noam Gavrielov, Amiram Leviatan, Francesco Iachello

摘要:

本文介绍了一种新的玻色-费米框架,用于研究组态混合下奇质量核的光谱性质和量子相变(QPT)。一个详细的分析奇质量铌同位素披露的影响,突然跨越国家在正常和入侵者的配置(II型QPT),伴随着一个逐渐演变的球形变形的核心形状内的入侵者配置(I型QPT)。这两种类型的QPT的明显存在表明,第一次,在奇质量核中发生纠缠的QPT。

英文摘要:

We introduce a new Bose-Fermi framework for studying spectral properties and quantum phase transitions (QPTs) in odd-mass nuclei, in the presence of configuration mixing. A detailed analysis of odd-mass Nb isotopes discloses the effects of an abrupt crossing of states in normal and intruder configurations (Type II QPT), accompanied by a gradual evolution from spherical- to deformed-core shapes within the intruder configuration (Type I QPT). The pronounced presence of both types of QPTs demonstrates, for the first time, the occurrence of intertwined QPTs in odd-mass nuclei.
