    Abstract

    In Cu2O a new absorption line is observed at 97 cm-1 below the n =1 of the yellow exciton (triply degenerate orthoexciton) under a strong magnetic field at 4.2 K. The line is assigned as a transition to a nondegenerate spin triplet state Γ+ 2 (paraexciton). An analysis including the effects due to the n =1 of the green exciton yields 364 cm-1 as the exchange energy, and 2.68 and -1.02, or 1.02 and -2.68 as the g-factors of the conduction and valence bands forming the yellow exciton. © 1977.
