Abstract
A method for solving the k-dependent positron Schrodinger equation has been developed, extending the numerical technique developed by Puska and Nieminen. It is possible to apply the present method to calculations of the positron band mass m*. Results for alkali metals and YBa2Cu3O7 are presented as examples.Keywords
