The wave function in multiple scattering theory

The wave function in Multiple Scattering Theory (MST) is a locally exact solution to the Schrodinger equation for any l truncation (lmax), except at the muffin-tin boundaries (or cell boundaries in a full cell calculation) where it and its derivative generally have discontinuities. These discontinuities vanish only in the limit lmax → ∞. Furthermore, the MST wave function as usually calculated is not correctly normalized which means the density of states calculated from the Green function does not agree with the calculated from the Lloyd formula. In this paper, the authors obtain an alternative wave function form the usual MST secular equation which is smooth and continuous everywhere and which is correctly normalized
