Abstract
We propose here a systematic and straightforward way to include point-group symmetries into the theory of photoelectron diffraction. In addition to re ducing the number of scattering path operators that have to be calculated, this approach permits as well as to derive a new algorithm to minimize the number of paths that have to be explored in the series expansion cluster me thod by making use of path degeneracies.
