消失流能量的系统研究:状态方程和截面的作用

Systematic study of the energy of vanishing flow: Role of equations of state and cross sections

Aman D. Sood, Rajeev K. Puri

摘要:

我们提出了一个系统的研究消失流的能量,考虑对称碰撞核($^{12}$ C和$^{238}$ U之间)在归一化的碰撞参量使用各种状态方程(有和没有动量相关的相互作用)以及不同的核子-核子截面。在所有的情况下,得到了一个完美的幂律质量依赖,通过计算点很好。此外,碰撞参量的选择显著地影响消失流的能量,要求非常精确地测量碰撞参量。然而,消失流的能量对状态方程及其动量依赖性不太敏感。

英文摘要:

We present a systematic study of the energy of vanishing flow by considering symmetric colliding nuclei (between $^{12}$C and $^{238}$U) at normalized impact parameters using variety of equations of state (with and without momentum dependent interactions) as well as different nucleon-nucleon cross sections. A perfect power law mass dependence is obtained in all the cases which passes through calculated points nicely. Further, the choice of impact parameter affects the energy of vanishing flow drastically, demanding a very accurate measurement of the impact parameter. However, the energy of vanishing flow is less sensitive towards the equation of state as well as its momentum dependence.
