清华大学物理系原子核结构实验研究进展

在清华大学百年校庆之际,我们对近年来清华大学物理系有关原子核结构实验研究的主要进展作一介绍,内容包括在A≈140缺中子核区核的形状驱动效应研究,如扁椭形变带、形状共存等;在A≈110丰中子核区核的多声子γ振动带结构、新手征二重带、新的准粒子带结构研究等;在A≈150丰中子核区核的八极形变研究等.研究成果对原子核结构的理解提供许多新的重要信息.

Progress in research on nuclear structure in Department of Physics, Tsinghua University

For the centenary celebration of Tsinghua University we give a brief review of the experimental research on nuclear structure by our research group in this article. The main research progress are： the shape driving effect in A≈140 neutron-deficient region, such as the oblate deformed bands, the shape coexistence etc.; the multi-phonon gamma vibrational bands, the new chiral doublet bands, the new quasi-particle bands etc. in A≈110 neutron-rich region; the octupole deformation etc. in A≈150 neutron-rich region. The research results provide new valuable information to understand the nuclear structure.
