Abstract
The light absorbtion coefficient of a semiconductor film caused by indirect electronic transitions is calculated under the assumption that the part of the third body plays a dislocation. There is obtained the frequency dependence of the absorbtion coefficient at various orientations of dislocations in the film. The comparison is carried out of the suggested mechanism with known mechanisms of indirect transitions.
