摘要/Abstract

摘要： 鉴于原子核碰撞理论计算的繁冗,提出一种用群论进行项分类的方法,它能分辨出散射振幅中贡献相同的积分项,简化计算,使便于编制计算程序,也节省了机时.具体计算了入射动量为5.07GeV/c的氦原子核在氦原子核上的弹性散射,结果是满意的.

关键词: 弹性碰撞, 微分截面, 置换群理论

Abstract: In view of the serious complexity of the calculation of nucleus-nucleus colli sion, a group theory method is proposed, by which the integrals with same value in the amplitude equation can be identified, and the calculation would become simple and easy to proceed on computer. The α-αelastic scattering at 5.07 GeV/c is calculated concretely and the result is satisfactory.

Key words: collision, differential cross section, permutation group theory method
