中能重离子碰撞中的自旋轨道耦合和上下微分横向流

Yin Xia, Jun Xu, Bao-An Li, Wen-Qing Shen

摘要:

为了探索介质中自旋轨道耦合的强度、同位旋依赖性和密度依赖性,这一耦合鲜为人知,但与理解稀有同位素的结构有关,在最近发展的一个自旋-同位旋相关输运模型中,通过改变Au+Au碰撞的束流能量和碰撞参量,系统地研究了核子自旋上下微分横向流。能量重离子碰撞。讨论了刻画和解开自旋轨道耦合中不同项效应的最佳反应条件。

英文摘要:

To explore the strength, isospin dependence, and density dependence of the in-medium spin-orbit coupling that is poorly known but relevant for understanding the structure of rare isotopes, the nucleon spin up-down differential transverse flow is studied systematically by varying the beam energy and impact parameter of Au+Au collisions within a spin-isospin dependent transport model recently developed for investigating spin-related phenomena in intermediate-energy heavy-ion collisions. The optimal reaction conditions for delineating and disentangling effects of different terms in the spin-orbit coupling are discussed.
