标题： Scattering of a spin-1/2 particle off a spin-0 target in a simple three-dimensional basis

摘要： 自旋为1/2的粒子与自旋为0的靶粒子的散射是基于简单的三维动量-自旋基来表述的。 势和T矩阵元的方位行为导致仅涉及动量大小和散射角两个变量的T矩阵元的一组积分方程。 势和T矩阵元的一些对称性关系将需要求解的积分方程数量减少了一半。 给出了以二维T矩阵元表示的全部自旋可观测量的列表。 显示英文摘要

摘要： Scattering of a spin-1/2 particle off a spin-0 target is formulated based on a simple three-dimensional momentum-spin basis. The azimuthal behaviour of both the potential and the T-matrix elements leads to a set of integral equations for the T-matrix elements in two variables only, namely the momentum's magnitude and the scattering angle. Some symmetry relations for the potential and the T-matrix elements reduce the number of the integral equations to be solved by a factor of one half. A complete list of the spin observables in terms of the two-dimensional T-matrix elements is presented.
