一种计算核子-核子散射可观测量的方法

A method for calculating nucleon-nucleon scattering observable

摘要:

对M矩阵进行参数化是一种计算核子-核子弹性散射可观测量的方法. M矩阵由于核子-核子相互作用的对称性，可以参数化为5个参数，可观测量可以由这5个参数得到. 本文介绍一种不需要对M矩阵参数化，直接使用总自旋和总自旋z分量表象下的M矩阵元计算可观测量的方法.

Abstract:

M-matrix parameterization is a method to calculate nucleon-nucleon elastic scattering observable. The M-matrix can be parameterized as 5 scattering amplitudes because of symmetry and observables can be calculated from these amplitudes. In this paper we introduce a way to calculate observable from M-matrix elements in total spin and total spin z component representation without parameterization.
