The characteristic delay, rise, and decay times of recombination radiation at high exciton densities (P∞-band) in CdSe monocrystal (77 K) were measured with 2-psec time resolution and found to be 34±6, 9±2, and 16±3 psec, respectively. The values of the rate constants of the exciton-exciton interaction and of the binding of free carriers into excitons were estimated.
