Comment on "Analytic Solution of the Relativistic Coulomb Problem for a Spinless Salpeter Equation"
arXiv:hep-ph/9401293
Abstract
We demonstrate that the analytic solution for the set of energy eigenvalues of the semi-relativistic Coulomb problem reported by B. and L. Durand is in clear conflict with an upper bound on the ground-state energy level derived by some straightforward variational procedure.
