利用同位旋相关的量子分子动力学 ,通过原子核阻止研究了中能重离子碰撞中动量相关作用对于同位旋相关的平均场 (对称势 )的重要性 .计算结果表明动量相关作用同时加强了原子核阻止对于对称势和核子 -核子碰撞截面同位旋效应的灵敏性 .但相对而言核子 -核子碰撞截面对于原子核阻止的作用远大于对称势对于它的作用 ,等价于动量相关作用提高了原子核阻止对于核子 -核子碰撞截面同位旋效应的灵敏性 ,而减弱了原子核阻止对于对称势的灵敏性 .这样就把原子核阻止作为提取同位旋相关的核子 -核子碰撞截面的一个探针
By means of isospin-related quantum molecular dynamics, we study the importance of momentum-related effects on isospin-dependent mean fields (symmetry potentials) in a heavy ion collisions by means of atomic nuclei. The calculated results show that the momentum-related effect strengthens the nuclear inhibition For the symmetry potential and the nucleon-nuclear collision cross-section isospin effect sensitivity, but relatively speaking, nuclear-nuclear impact cross section of the role of nuclear inhibition is much larger than the symmetrical potential for its role, equivalent to the momentum-related action to improve the nucleus to prevent The sensitivity of the nucleus to stop the symmetry potential is reduced by the sensitivity of the isonuclear-nucleon-collisional isospin effect, thus preventing the nucleus from acting as a probe for the extraction of the isospin-dependent nuclear-nuclear collision cross-section
