Chemistry and Pharmacology
The complete spectrum emitted by a conventional X-ray diffraction Cu target produces damage in a small TGS crystal which is evident from the variation of integrated intensities of X-ray reflexions with irradiation time. An interpretation of the data is proposed which assumes that the trapping of irradiation products causes an exponential decrease of mosaic-block diameters. An empirical correction of the Zachariasen extinction factor for crystals belonging to type II is suggested, since the TGS crystal is of this type.
