用丰中子核引起的重离子反应探测核对称能

Lie-Wen Chen, Che Ming Ko, Bao-An Li, Gao-Chan Yong

摘要:

丰中子核诱导的重离子反应为研究同位旋非对称核物质的物态方程,特别是核对称能的密度依赖性提供了一种独特的手段。特别是,最近的重离子反应中的同位旋扩散数据的分析已经提出了一个严格的约束周围的核物质饱和密度的核对称能。我们回顾了这一令人兴奋的结果,并讨论了它对核有效相互作用和重核中子皮厚度的影响。此外,还综述了高能放射性核束诱发重离子反应中核对称能高密度行为的理论研究进展。

英文摘要:

Heavy-ion reactions induced by neutron-rich nuclei provide a unique means to investigate the equation of state of isospin-asymmetric nuclear matter, especially the density dependence of the nuclear symmetry energy. In particular, recent analyses of the isospin diffusion data in heavy-ion reactions have already put a stringent constraint on the nuclear symmetry energy around the nuclear matter saturation density. We review this exciting result and discuss its implications on nuclear effective interactions and the neutron skin thickness of heavy nuclei. In addition, we also review the theoretical progress on probing the high density behaviors of the nuclear symmetry energy in heavy-ion reactions induced by high energy radioactive beams.
