The interaction of a free, thermalized electron with a CT exciton (nearest‐neighbor hole–electron pair) in an anthracene crystal is discussed theoretically. The rate constant for the annihilation of the CT exciton by the electron, in which an Auger electron is produced in a plane‐wave crystal state by the decay of an intermediate excitonic ion state is estimated to be about 10 −10 to 10 −9 cm 3 S −1 .
