In two recent papers, an isometric conformal transformation has beenintroduced that eliminates potential interaction terms from the Schr\"odingerequation for central potential problems. The method has been demonstrated forboth the hydrogen atom and three-dimensional harmonic oscillator. Here, it isshown that the same transformation technique can also be applied to centralpotential problems formulated using the Klein-Gordon equation.
