Abstract
We construct the expansion of a Bloch wave with energy E into a complete set of multipole waves around a ’’center’’ of a crystal as an analog of the expansion in spherical waves in free space. Crystal point group symmetry is used to classify the set. The density of states in a cell is then analyzed into multipole components whose magnitude depends on the cell’s distance from the ’’center.’’Keywords
