Abstract
A monocrystalline Bi.sub.2 Ge.sub.3 O.sub.9 is formed, for example, via the Czochralski technique from a melt containing pure Bi.sub.2 O.sub.3 and GeO.sub.2 at a molecular ratio of 1:3. This crystal is useful as an x-ray spectrometer crystal and/or as a light defector crystal in conjunction with an ultrasonic deflection field properly applied to such crystals.
