Abstract
In 1953 Slater proposed a linearized version of the APW method based on the augmented basis functions with continuous function values and first derivatives at the muffin-tin radius. This paper describes a modification of this method and a numerical scheme which makes it suitable for practical band structure calculations. As an example, the energy structure of Cu is evaluated.
