【摘要】 我们试图在刚性炮弹近似下,用Glauber方法研究高能核-核碰撞过程。本文具体处理了137GeV的α粒子和¹²C的弹性散射,认为α-¹²C的散射是由α粒子与靶核¹²C内的核子-核子多重散射过程。我们没有引入任何可调参数。计算的微分截面与实验结果进行了比较,符合是满意的,从而支持了多重散射的机制。更多还原

【Abstract】 Based on the "Rigid Projectile" Approximation, we have analyzed the Saclay data on the elastic scattering of alpha ¹²C. At the energy T_a^lab=1.37 GeV. Using the Glauber’s multiple scattering theory, we assume that ⁴He-¹²C scattering is a multiple scattering process between nucleons in projectile ⁴He and target nucleus ¹²C. We don’t introduce any free parameter in our calculation. The theoretical differential cross sections are compared with the experimental one. The agreement is satisfactory. It supports strongly the multiple scattering mechanism we have assumed.更多还原
