• Exciton polarons dressed with a cloud made of several phonons exist as a newphase in the f.c.c. lattice between the phase of self-trapped excitons dressed withmuch more phonons and that of free excitons essentially undressed. The excitonpolaron in the new phase moves slowly resonating among localized polaron stateswhose phonon cloud has a symmetry of two-center type centered at each pairof nearest-neighbor sites. This phase cannot be obtained in the s.c. lattice wherea pair of nearest neighbors have no common nearest neighbors. The exciton-phonon interaction modifying the transfer integral of exciton must have anintermediate strength in order for this phase to be realized. It can be ascribed tothis phase that in a mixed crystal of AgBr.-.Cl, where silver or halogen tonsconstitute the f.c.c. sublattice phonon replicas in the luminescence spectrumpeak at a line of the severalth order for x-aO.45 just before the self-trapped stateis stabilized.
