摘要:

本研究首次采用三维空间格点上的含时倾斜轴推转协变密度泛函理论,以微观自洽的方式研究了软三轴核中的手征性。以存在争议的手征核$^{106}$Ag为例,除明确定义的密度泛函外未引入任何自由参数,就很好地重现了观测到的近简并带的实验能级。从总角动量的微观动力学中,新揭示了软三轴核中的一种新型手征模式。这为手征性研究开辟了新领域,尤其是与软核形状相关的研究。

英文摘要:

The chirality in soft triaxial nuclei is investigated for the first time with the time-dependent and tilted axis cranking covariant density functional theories on a three-dimensional space lattice in a microscopic and self-consistent way. Taking the puzzling chiral nucleus $^{106}$Ag as an example, the experimental energies of the observed nearly degenerate bands are well reproduced without any free parameters beyond the well-defined density functional. A novel chiral mode in soft triaxial nuclei is newly revealed from the microscopic dynamics of the total angular momentum. This opens a new research area for the study of chirality, particularly in relation to soft nuclear shapes.
