由于质子与中子不同的形状驱动效应影响,A=130缺中子核区的核在高自旋态下可呈现丰富多彩的核结构特性,如形状共存、扁椭形变、旋称反转、手征二重带结构等。对双奇核122Cs与136La进行了高自旋态研究,目的是在122Cs中寻找手征二重带,在136La中研究旋称反转与扁椭形变特性。实验
Due to the different shape-driven effects of protons and neutrons, the nuclei of A = 130 neutron nucleus can exhibit rich and varied nuclear structural features under high spin states such as shape coexistence, flattened oval change, spin inversion, chirality Double belt structure and so on. The high spin states of 122Cs and 136La were investigated for the purpose of finding the chiral double bands in 122Cs and studying the spin inversion and flat oval deformation in 136La. experiment
