In addition to visualizing the crystal structure in three dimensions, using VRML enables one to move and rotate it. It is also possible to virtually step inside the lattice or the structure and to examine them from there. The pseudo three-dimensional drawing of the tmaYs02o crystal structure on the CD was ereated using the General Structure Analysis System (GSAS), and...

All computations described in the following five sections have been performed using GSAS (General Structure Analysis System), one of the most advanced implementations of the Rietveld refinement approach... 

A.C. Larson and R.B. Von Dreele, General Structure Analysis System (GSAS), Los Alamos National Laboratory Report, LAUR 86-748 (2000). Although GSAS is suitable for treatment of both powder diffraction and single crystal data, in the context of this book we are chiefly concerned with its capabilities to processing powder data. 

The structural parameters of ordered ice V (ice XIII) were refined by using the General Structure Analysis System (GSAS) program,by using the values for disordered ice V as...

TRD-analysis was carried out with the use of XRD diffractometer DRON-3.0 with Cu-K irradiation (X = 1.5405 nm). Data have been analyzed by full-profile revision in accordance withthe/i/YveWS method with the use of the simulation package GSAS (General Structure Analysis System).
