Studies on the Signature Inversion in Doubly Nuclei ^(118)Cs,^(120)Cs,^(122)Cs,^(124)Cs and ^(126)Cs

作者利用二准粒子 +三轴形变转子模型 ,计算了1 1 8Cs,1 2 0 Cs,1 2 2 Cs,1 2 4 Cs和1 2 6Cs 5个双奇核的晕带能谱 ,理论结果与实验符合较好 .研究表明 ,该理论模型中的科氏力与质子 中子相互作用的竞争是旋称反转的可能机制 ;同时 ,三轴形变对旋称反转的影响因素也很重要 ,应予以考虑 .

The yrast bands of doubly nuclei 118Cs, 120Cs, 122Cs, 124Cs and 126Cs have been calculated within the two quasi-particles plus tri-axially deformed rotor model and the the theoretical results coincide with the experiment well. The research indicates that,in the theoretical model,the competition between the proton-neutron interaction and the Coriolis force is the probable mechanism of signature inversion,and the effect of tri-axial deformation on the signature inversion is also important and should be considered.
