<i>EXPO</i>: a program for full powder pattern decomposition and crystal structure solution

Abstract

EXPO is the integration of two programs, EXTRA and SIRPOW.92 , the first devoted to full powder pattern decomposition and the second to the solution and refinement of crystal structures. The program is able to exploit the prior information obtained during the crystal structure solution process for improving the classical decomposition. EXPO also allows preliminary cycles of Rietveld refinement.
