Approximation has been made to the centrifugal term and space-time transformation is used to deal easily with the difficult computation problem. We found that there are positive energy states for bound states based on the condition for the wave functions. The results are in agreement with those obtained by using other methods found in the literature.enRadial propagatorEnergy spectrumWavefunctionsKlein-Gordon equationFeynman methodModified second type Pö schl-TellerpotentialLimit statesArticle
