摘要:

我们将我们的方法,将质子-质子(PP)库仑力到三核子(3 N)动量空间Faddeev计算的弹性质子-氘(PD)散射和分裂的情况下,也有一个三核子力(3 NF)的作用。此外,我们制定的方法中的应用程序中的电子和γ-诱导反应的3 He。主要的新成分是一个3维屏蔽pp库仑t-矩阵通过一个3维Lippmann-Schwinger方程(LSE)的数值解。所得方程具有与描述没有3 NF作用的pd散射的Faddeev方程相同的结构。这表明了两种公式的实际可行性。

英文摘要:

We extend our approach to incorporate the proton-proton (pp) Coulomb force into the three-nucleon (3N) momentum-space Faddeev calculations of elastic proton-deuteron (pd) scattering and breakup to the case when also a three-nucleon force (3NF) is acting. In addition we formulate that approach in the application to electron- and gamma-induced reactions on 3He. The main new ingredient is a 3-dimensional screened pp Coulomb t-matrix obtained by a numerical solution of a 3-dimensional Lippmann-Schwinger equation (LSE). The resulting equations have the same structure as the Faddeev equations which describe pd scattering without 3NF acting. That shows the practical feasibility of both presented formulations.
