We study new structures peaked at the giant two-photon absorption (GTA) of biexcitons and peaked at ℏω-i$/ p in the exciton region which appear in the excitation spectrum for the emission at ℏω-s$/ of the biexciton origin in CuCl at 2 K in the excitation photon density of approximately 5Mw/cm 2 . An energy relation, ℏω-i$/ p approximately ℏω-s$/ + E m b + Δ LT is obtained, wher E m b and Δ LT · are the binding energy of a biexciton and the L-T splitting energy of an exciton, respectively. Existence of a complex of biexciton-polariton or triexciton is implied as an interpretation of this phenomenum. Discussion is presented in relation to the broad band at GTA.
