摘要：

We devise and apply a method for the calculation of the exact propagator for the Schrodinger equation for the one-dimensional Hamiltonian H(p,x)=p2/2m + V0THETA(x). The limiting cases V0 --> 0 (free particle) and V0 --> infinity (opaque wall) are checked. The method is also applicable to any piecewise-constant potential.
