摘要：

A simple and easily implemented highly accurate method to compute the scattering length and effective range for a diatomic potential is presented. It combines the numerical solution for small internuclear distances R with analytical corrections for large R. The method provides upper and lower limits to the exact values, to any desired precision. A numerical example and discussion are given for the case of the Cs-Cs ground-state interaction.
