Bethe-Salpeter方程的渐近逼近及其对氘核的应用

Asymptotic Approximation for Bethe-Salpeter Equation and its Applications to Deuteron

Susumu Kinpara

摘要:

求解了赝矢量耦合的π交换力作用下两个费米子组成的束缚态的Bethe-Salpeter方程。将振幅用伽玛矩阵展开,导出了一维积分方程。它再现了氘核的结合能。在渐近近似的框架下讨论了与四极矩的关系。

英文摘要:

Bethe-Salpeter equation is solved for bound state composed of two fermions mediated by pion exchange force of the pseudovector coupling. Expanding the amplitude by gamma matrices the one-dimensional integral equation is derived. It reproduces the binding energy of deuteron. The relation with the quadrupole moment is also discussed in the framework of the asymptotic approximation.
