Abstract.

This work explores the application of perturbation formalism, developed for isotropic velocity-dependent potentials, to three-dimensional Schrödinger equations obtained using different orderings of the Hamiltonian. It is found that the formalism is applicable to Schrödinger equations corresponding to three possible ordering ambiguities. The validity of the derived expressions is verified by considering examples admitting exact solutions. The perturbative results agree quite well with the exactly obtained ones.
