stacking fault models in GSAS

2001-07-04 Thread Andreas Leineweber
Dear all, has anyone information about the option to "apply a stacking fault model" when one changes the anisotropic broadening axis with "A" in the profile coefficients menue of GSAS? It is explained only quite vaguely in the manual. Does anyone know according to which reference the "stacking s

Debye Temperature & Lattice Thermal Expansion

2001-07-04 Thread Alexandros Lappas
    I wonder whether someone can help me with the following problem.   That is, I would like to know if there is a way to estimate the Debye temperature from crystal lattice thermal expansion.   I know that there is literature, and I have found the appropriate relations on how to calculate
