Abstract
An algorithm is described that seeks out Schrodinger eigenvalues Enl for a given central potential V(r). The algorithm has, in principle, arbitrary precision. A particular implementation has absolute error mod E-Enl mod decreasing as T-3, where T is machine computing time. The method is tested on the central Gaussian potential V(r)=-A exp(- lambda r2) of recent interest.Keywords
