3D Faddeev方案中自旋-同位旋相关的3 N散射形式

A Spin-Isospin Dependent 3N Scattering Formalism in a 3D Faddeev Scheme

M. Harzchi, S. Bayegan

摘要:

我们介绍了一种自旋-同位旋相关的三维方法来描述三核子散射。Faddeev方程用核子的矢量雅可比动量和自旋-同位旋量子数表示。我们的形式主义是基于连接的过渡振幅$T$的动量螺旋表示的两体$t$矩阵和氘波函数。最后给出了核子-氘核弹性散射和完全破裂过程振幅的表达式。

英文摘要:

We have introduced a spin-isospin dependent three-dimensional approach for formulation of the three-nucleon scattering. Faddeev equation is expressed in terms of vector Jacobi momenta and spin-isospin quantum numbers of each nucleon. Our formalism is based on connecting the transition amplitude $T$ to momentum-helicity representations of the two-body $t$-matrix and the deuteron wave function. Finally the expressions for nucleon-deuteron elastic scattering and full breakup process amplitudes are presented.
