手征核的转动动力学

Dynamics of rotation in chiral nuclei

Z. X. Ren, P. W. Zhao, J. Meng

摘要:

首次在三维空间格点上用含时斜轴推转协变密度泛函理论对手征核动力学进行了微观自洽研究。在没有任何可调参数的情况下,我们很好地再现了$^{135}$ Nd中两对手征双重带的实验能量。一种新的机制,即,手征旋进,揭示了从微观动力学的总角动量在体固定框架,其调和性是与过渡从平面到aplanar旋转与增加自旋。这为理解原子核中的手征激发提供了一个完全微观和动力学的视角。

英文摘要:

The dynamics of chiral 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. The experimental energies of the two pairs of the chiral doublet bands in $^{135}$Nd are well reproduced without any adjustable parameters beyond the well-defined density functional. A novel mechanism, i.e., chiral precession, is revealed from the microscopic dynamics of the total angular momentum in the body-fixed frame, whose harmonicity is associated with a transition from the planar into aplanar rotations with the increasing spin. This provides a fully microscopic and dynamical view to understand the chiral excitations in nuclei.
