Potential Scattering in Dirac Field Theory
arXiv:0908.2946 · doi:10.1140/epjc/s10052-009-1059-2
Abstract
We develop the potential scattering of a spinor within the context of perturbation field theory. As an application, we reproduce, up to second order in the potential, the diffusion results for a potential barrier of quantum mechanics. An immediate consequence is a simple generalization to arbitrary potential forms, a feature not possible in quantum mechanics.
