超流核中的轨道和自旋剪刀模

Orbital and spin scissors modes in superfluid nuclei

E. B. Balbutsev, I. V. Molodtsova, P. Schuck

摘要:

在同时考虑自旋自由度和对关联的广义Wigner函数矩方法框架下研究核剪刀模。发现了一种新的核磁性源,它与围绕对称轴上下反转的自旋(隐藏角动量)有关。它的列入理论允许一个显着改善的协议与实验数据在描述的能量和跃迁几率的剪刀模式在稀土原子核。

英文摘要:

Nuclear scissors modes are considered in the frame of Wigner function moments method generalized to take into account spin degrees of freedom and pair correlations simultaneously. A new source of nuclear magnetism, connected with counter-rotation of spins up and down around the symmetry axis (hidden angular momenta), is discovered. Its inclusion into the theory allows one to improve substantially the agreement with experimental data in the description of energies and transition probabilities of scissors modes in rare earth nuclei.
