S. Bruce et L. Roa, A DIRAC PARTICLE IN A VECTOR-LIKE HYDROGENIC POTENTIAL, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 111(2), 1998, pp. 159-164
We consider a new type of vector-like interaction in the Dirac equatio
n. Under minimal substitution the wave equation takes on a hydrogen-li
ke form. The eigenfunctions of the system are given and the degeneracy
of the eigenvalues is discussed.
