Using the one-photon counting method, we observed in the spectrum of the intrinsic luminescence of pure anthracene crystals, at 4.2 °K, lines with different damping and growth times. It is assumed that the anthracene crystal contains excitons of two types, and that at low temperature the energy transfer is from the excitons of the first type to those of the second, and from the latter to the impurities.
