| Abstract: | The optical alignment of hot electrons and its destruction in a magnetic field under conditions when electron scattering by
neutral acceptors plays a large role is investigated. This makes it possible to determine the probability of the scattering
of hot electrons from an initial photoexcited state, as well as the times characterizing the energy and momentum relaxation
of hot electrons on scattering by neutral acceptors. The experimental results are compared with calculations.
