Abstract
We report the observation of inverse exciton series (M-emission series) in the optical decay of an excitonic molecule to the exciton excited states (n = 2s, 3s, and its). A theory is developed which relates the inverse excito n series to the molecule wave function using the bipolariton model. The com ponents of the exciton excited states n = 2, 3, and 4 in the biexciton wave function in CuCl are determined from the relative intensities of M-1s, M-2 s, M-3s, and M-4s emission lines. This opens a way to reconstruct the inter nal molecule wave function. [S0163-1829(99)50412-8].
