Observing renewed interest in long-standing (semi-) relativistic descriptions of two-body bound states, we would like to make a few comments on the eigenvalue problem posed by the spinless Salpeter equation and, illustrated by the examples of the nonsingular Woods-Saxon potential and the singular Hulthen potential, recall elementary tools that, in their quest, practitioners looking for analytic albeit approximate solutions will find useful.

Semirelativistic Bound States: (Pseudo-) Spinless-Salpeter Approaches Reassessed
Relativistic quantum field theory offers, in form of the homogeneous Bethe-Salpeter framework, a (Poincare-covariant) description of bound states in terms of their underlying theory's fundamental…
The spinless relativistic Hellmann problem
We compile some easily deducible information on the discrete eigenvalue spectra of spinless Salpeter equations encompassing, besides a relativistic kinetic term, interactions which are expressible as…
Higher order Schrodinger and Hartree-Fock equations
The domain of validity of the higher-order Schrodinger equations is analyzed for harmonic-oscillator and Coulomb potentials as typical examples. Then, the Cauchy theory for higher-order Hartree–Fock…
Relativistic two fermion treatment of hyperfine transitions
A system of two fermions with different masses and interacting by the Coulomb potential is presented in a completely covariant framework. The spin–spin interaction, including the anomalous magnetic…

TLDR
The existence of non-trivial solutions for the following equation is considered and it is shown that problem (1) admits at least a solution provided that in the case of J being odd, the solution is small.
The Spinless Relativistic Kink-Like Problem
We constrain the possible bound-state solutions of the spinless Salpeter equation (the most obvious semirelativistic generalization of the nonrelativistic Schr\"odinger equation) with an interaction…

TLDR
The spinless relativistic Coulomb problem is the bound-state problem for the spinless Salpeter equation with the Coulomb interaction potential with the static limit of the exchange of some massless bosons, as present in unbroken gauge theories.
