Abstract
Two pulse photon echoes of B-carotene in ethanol solution have been in vestigated for various temperatures with incoherent laser light. The d ecay time of the echo intensity increases with decreasing temperature. The results are compared with a model calculation of the echo assumin g a spectrum for the phonon density of states.
