Green Function for Spin 1/2 particle in a Coulomb + Scalar Potential
arXiv:hep-th/0203133
Abstract
We calculate the Green function for the Dirac equation describing a spin 1/2 particle in the presence of a potential which is a sum of the Coulomb potential V_C=-A_1/r and a Lorentz scalar potential V_S=-A_2/r. The bound state spectrum is obtained.
