✦ Synopsis

Nature of the physical problem PROVA calculates the X-ray intensity diffracted from powders constituted by generic domains, whatever the dimensions of each domain along the three crystallographic axes, possibly disordered, having unit cells belonging to any crystal system.

Method of solution

The calculation of the powder X-ray intensity requires the evaluation of one surface integral for each point of the calculated spectrum. In PROVA, the integration is performed by the Gauss method.
