Abstract
A modified difference and a Numerov-like scheme have been introduced i n a shooting algorithm for the determination of the (higher-lying) eig envalues of Schrodinger equations and Sturm-Liouville problems. Some n umerical experiments are introduced. Time measurements have been perfo rmed. The proposed algorithms are compared with other previously intro duced shooting schemes. The structure of the eigenvalue error is discu ssed.
