Abstract

By use of simple mathematical transformations, an integral equation for the Greens function method leads to a homogeneous equation which contains only the nonsingular part of the Greens function. No limitations are imposed on the crystal potential, so the solutions may be found for any unit cell. The method is applicable to any crystal structure. Using bcc iron as an example we present various calculations which make it possible to predict ahead of time which atomic levels will form bands and which will not.
