摘要

采用最新开发的碰撞磨损-烧蚀蒙特卡罗(AAMCC)模型，计算了197Au - 197Au和208Pb - 208Pb在中心(0-5%中心)碰撞中产生的旁观物质的性质，这些碰撞能量为核电子离子对撞机设施(NICA)加速器的典型能量。证明了旁观中子发射截面对197Au的核变形和208Pb中中子蒙皮的敏感性。研究了197Au的核变形对自由旁观核子的前后不对称性和旁观物质总量的不对称性的影响。

Spectator nucleons in most central collisions of heavy nuclei at NICA

Properties of spectator matter created in central (of 0-5% centrality) 197Au– 197Au and 208Pb– 208Pb collisions with energies typical for the Nuclotron based Ion Collider fAcility (NICA) accelerator complex are calculated with a recently developed Abrasion-Ablation Monte Carlo for Colliders (AAMCC) model. The sensitivity of cross-sections of emission of spectator neutrons to the nuclear deformation of 197Au and to the presence of neutron skin in 208Pb is demonstrated. The influence of the nuclear deformation of the 197Au on the forward-backward asymmetry of free spectator nucleons and on the asymmetry of the total volume of spectator matter is investigated.
