| 摘 要： | 在多源理想气体模型的框架内,用解析和蒙特卡洛两种方法计算分析了中能重离子碰撞中末态核碎片的方位角分布和椭圆流对横动量的依赖关系,并由此分析了末态核碎片的各向异性分布特征。对计算结果与同位旋依赖的的量子分子动力学(ISQMD)模型的计算结果进行了比较,发现二者基本符合。

| Abstract: | In the framework of the Multi-Source Ideal Gas Model,the azimuthal distributions of final-state nuclear fragments and the dependences of their elliptic flows on transverse momentum are calculated by using the analytic and Monte Carlo methods.The properties of anisotropic distributions for nuclear fragments produced in heavy ion collisions at intermediate energy are analyzed.Our calculated results are compared and found to be in agreement with the results of the Isospin Dependence Quantum Molecular Dynamical... |
