Abstract
The method of analysis of double spectrometer rocking curves developed by L. P. Smith is reconsidered. Although from Smith's very general viewpoint, six experimental curves are needed for a complete analysis, it is shown that for rocking curves from calcite, taken with the usual type of double spectrometer, it should be possible to deduce the shape of the single crystal diffraction pattern from two rocking curves, the (1,+1) and (2,+2). A method of modifying the equations of the instrument to allow for a simple type of mosaic structure is indicated.
