Utilizing an appropriate ansatz to the wave function, we
reproduce the exact bound-state solutions of the radial Schrödinger
equation to various exactly solvable sextic anharmonic oscillator and
confining perturbed Coulomb models in D-dimensions. We show that the
perturbed Coulomb problem with eigenvalue E can be transformed to a
sextic anharmonic oscillator problem with eigenvalue .
We also check the explicit relevance of these two related problems in
higher-space dimensions. It is shown that exact solutions of these
potentials exist when their coupling parameters with k = D +2ℓ appearing
in the wave equation satisfy certain constraints.
