There are several aspects of the single crystal, self-absorption, source technique that have needed further analysis. In this report we will explain our calculational study designed to improve our theoretical model by incorporating a gaussian, source distribution and including solid angle effects. Our current experiments have been done in the vertical geometry. i.e. the single crystal is lying flat and the Ge detector is positioned below. In this configuration there are two solid angle effects not only the fact that different sample slices subtend slightly different solid angles at the detector, but also the fact that, due to the contraction of the dewar-sample system itself, an overall temperature dependent solid angle effect is produced.
