Abstract

Both the WKB and the supersymmetric WKB (SWKB) approximations have been applied to the finite square-well potential and compared with the corresponding exact results. Even though this potential is not shape-invariant, an analytic expression for the superpotential is possible and it is seen that the SWKB is better than the WKB for almost all states.
