Barrier penetration for supersymmetric shape-invariant potentials

Exact reflection and transmission coefficients for supersymmetric shape-invariant potentials barriers are calculated by an analytical continuation of the asymptotic wavefunctions obtained via the introduction of new generalized ladder operators. The general form of the wavefunction is obtained by the use of the F (-infty ,+infty )-matrix formalism of Fröman and Fröman which is related to the evolution of asymptotic wavefunction coefficients.
