Abstract
A numerical method is presented for calculating the quantum-mechanical transmission coefficient of one-dimensional problems with potentials of arbitrary shapes. The method is demonstrated to give very accurate results on two solvable examples. The numerical error in the calculate d transmission coefficient is proportional to the second power of inte gration step size for potentials without discontinuities; for potentia ls with discontinuities, the dependence is linear.
