同位旋相关截面对核阻止的影响

Effect of isospin dependent cross-section on nuclear stopping

Anupriya Jain, Suneel Kumar

摘要:

利用核子动量分布的快度分布和不对称性研究了重离子碰撞(HIC)中的核阻止。它是决定反应结果的一个重要量。傅芬{ \it等,} \cite{2}计算了Pb + Pb和Ni + Ni在0.4、0.8和1.2GeV/核子的径向流和核阻止度。他们发现,在所有能量下,较重系统的膨胀速度和核停止程度都较高。

英文摘要:

Nuclear stopping in heavy ion collisions (HIC) has been studied by means of rapidity distribution and asymmetry of nucleon momentum distribution. It is an important quantity in determining the outcome of a reaction. Fen Fu {\it et al.,} \cite{2} calculate both the radial flow and the degree of nuclear stopping in Pb + Pb and Ni + Ni at 0.4, 0.8 and 1.2 GeV/neucleon. They found that the expansion velocity as well as the degree of nuclear stopping are higher in the heavier system at all energies.
