主 题:Secondary extinction X-ray diffraction Neutron diffraction
摘 要:Universal expressions for the secondary extinction factor in X-ray andneutron crystallography are developed,based on an exact solution of the power transferequations using three dimensionless *** a demonstration of the feasibility ofthese expressions,the long-debated problem of diffraction in a large lithium fluoridesingle crystal is reanalyzed by using Lawrence’s data set,with all the hitherto omittedstrong reflections (Y down to 0.20) included,and a R factor value of less than 0.014 isobtained.
