Zeeman Effect of an Induced Absorption Line in Highly Excited CuCl

Abstract

Zeeman effect is studied for a narrow absorption line at 390.89 nm in CuCl crystal induced by a nitrogen laser excitation, the appearance of which was reported previously as a possible evidence for the Bose condensation of excitons. From the Zeeman splitting, it is concluded that this absorption corresponds to the formation of an exciton bound to a transiently generated neutral donor.
