Dear All My questions concerns Stephen's anisotropic microstrain parameters in GSAS' profile function no. 4. Are negative values of these parameters (Shkl)) acceptable, i.e. do they have any physical/chemical meaning? In case negative values are not "allowed", how should one proceed (e.g. fix the ill parameters to 0?)?
Thanks for your advice. Franz Werner -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger?did=10
