WebAbstract. The electron density function ρ (r) in a crystal determines its diffraction pattern, that is, both the magnitudes and phases of its x-ray diffraction maxima, and conversely. If, however, as is always the case, only magnitudes are available from the diffraction experiment, then the density function ρ (r) cannot be recovered. WebSep 20, 2024 · Direct conversion Direct conversion is so named because this technique directly converts the absorbed x-ray into a proportionally sized electrical charge with no intermediate scintillating step. This technique employs a semiconductor material which produces electron-hole pairs in proportion to the incident x-ray intensity.
