High-spin states in 152Eu have been studied using the 150Nd (7Li, 5n) reaction at a beam energy of 42 MeV. Five rotational bands together with several strong electric dipole transitions linking the positive- and negative-parity bands have been identified and interpreted as multiple octupole correlation effects originating from the octupole interactions between valence protons and valence neutrons respectively. The coexistence and interaction of octupole correlation effects caused by the interaction of valence protons and valence neutrons are discussed. 

报告人简介

刘晨，山东大学副教授，硕士研究生导师。长期从事原子核结构的实验研究工作，在原子核对称性及自发对称性破缺的实验和理论研究方面取得了一系列成果：首次观测到原子核中手性和空间反射对称性的联立自发破缺；建议了原子核中手征对称性与其他对称性联立自发破缺的候选核；实验上扩展了80质量区手征岛；对100和190质量区手性原子核开展实验和理论研究，排除了108Ag中手征性的解释，建议了Tl同位素中的手征候选核；研制核探测器，丰富了我国核谱学测量手段等。申请人迄今为止共发表SCI文章41篇，包括3篇PRL，其中以第一作者发表的PRL文章被遴选为封面文章。主持国家自然科学基金面上、青年、山东省自然科学基金优秀青年基金等项目共9项。
