Fundamental aspects related to the calculation of phase shifts and XAFS signals in the PHAGEN and GNXAS programs in the GNXAS package are reviewed. The strategies behind multiple-scattering series and decomposition into irreducible n-body signals are illustrated.

Abstract

Fundamental aspects related to the calculation of phase shifts and XAFS signals in the PHAGEN and GNXAS programs in the GNXAS package are reviewed. The strategies behind multiple-scattering series and decomposition into irreducible n-body signals are illustrated. The main strengths of the codes and the input/output data flow facilitated by the CRYMOL and GNPEAK programs are described.
