A theory is presented of the electronic Raman scattering on shallow donor levels in three-band semiconductors with direct band gaps. Explicit expressions of the matrix elements of the transitions from the ground state to the first excited state and to the states of the continuous spectrum are derived. It is shown that the most important contribution to these matrix elements comes from the intermediate states in the higher conduction band and in the valence band.Eine Theorie der elektronischen Ramanstreuung fur den flachen Donator in einem Drei-Band-Halbleiter mit direkter Bandstruktur wird behandelt. Explizite Formeln der Matrixelemente der tfbergange vom Grundzustand in den ersten Anregungszustand und zu dem Kontinuumspektrum werden angegeben. Es wird gezeigt, da13 die Zwischenzustande in dem hoheren Leitungsband und Valenzband den wichtigsten Beitrag fur diese Matrixelemente liefern.
