八极集体哈密顿量。它是否遵循四极子的例子?

The octupole collective Hamiltonian. Does it follow the example of the quadrupole case?

S. G. Rohozinski, L. Prochniak

摘要:

在七维张量空间中,从基本张量出发,引入并分析了八极集体哈密顿量的一般形式。考虑了八极张量具有立方对称性的内禀参照系的可能定义。引入了三次内禀八极坐标或形变。研究了八极体的对称性。八极集体哈密顿量用内禀坐标表示。发现了八极振动携带的内禀角动量。分析了轴对称梨形系统的小振荡。本文讨论了四极-八极统一的集体模型。

英文摘要:

A general form of the octupole collective Hamiltonian is introduced and analyzed based on fundamental tensors in the seven-dimensional tensor space. Possible definitions of intrinsic frames of reference possessing cubic symmetry for the octupole tensor are considered. Cubic intrinsic octupole coordinates or deformations are introduced. Shapes of the octupoloid are investigated. The octupole collective Hamiltonian is expressed in intrinsic coordinates. An intrinsic angular momentum carried by the octupole vibrations is discovered. Small oscillations about an axially-symmetric pear shape are analyzed. Formulation of a unified quadrupole-octupole collective model is discussed.
