Abstract:
This article uses the supersymmetric WKB approximation to obtain the approximate energy levels and wave functions of the anharmonic potential V(r) = ar2 br-4 cr-6 in order to tesify the correctness between Phys.Lett. A 170 (1992) 335] and the paper written by M. Landtman Phys. Lett. A 175 (1993) 147].
