  With the consideration of spherical symmetry for the potential and mass
function, one-dimensional solutions of non-relativistic Schrodinger equations
with spatially varying effective mass are successfully extended to arbitrary
dimensions within the frame of recently developed elegant non-perturbative
technique, where the BenDaniel-Duke effective Hamiltonian in one-dimension is
assumed like the unperturbed piece, leading to well-known solutions, whereas
the modification term due to possible use of other effective Hamiltonians in
one-dimension and, together with, the corrections coming from the treatments in
higher dimensions are considered as an additional term like the perturbation.
Application of the model and its generalization for the completeness are
discussed.
