Feynman Integral Treatment of the Deng-Fan Potential With a Centrifugal Term Approximation

Abstract
We present a rigorous path integral of a dynamical system in the Deng-Fan potential. To this end, an approximation of the centrifugal potential for any 􀜔 state is used and nonlinear space-time transformations in the radial path integral are applied. The exact bound state energy eigenvalues and the corresponding eigenfunctions are obtained for a particle bound on the various values of the quantum numbers 􀜖 and 􀜔 and compared to those of Schrodinger formalism. Index Terms—Deng-Fan potential, Space-time transformation, Propagator, Centrifugal potential.
