Paper Abstract

We study new structures peaked at the giant two-photon absorption (GTA) of biexcitons and peaked at h1P in the exciton region which appear in the excitation spectrum for the emission at h w of the biexciton origin in CuC1 at 2 K in the excitation photon density of ' 5Mw/cm2. An energy relation, thw1P . + ALT is obtained, where b and ALT 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.
