  We report theoretical and experimental study on Auger decay of excitons in
Cuprous Oxide in a wide range of temperatures, from 2 Kelvin to 325 Kelvin, in
single-photon surface excitation. We find that the Auger constant linearly
increases with temperature above 100 Kelvin. This constant is important for
experiments on Bose condensation of excitons.
