On the green function calculation for heavy quarkonium potential models
A new method for numerical calculation of the Green functions of the Schrödinger equation is proposed in the case of spherically symmetric potentials. This method can be applied to the potentials describing heavy quarkonium as well as to other problems of quantum mechanics. The case of the Coulomb potential with a running coupling constant is considered in detail. © 1986.
