摘要：
Two new bands were observed in luminescence spectrum of high-purity Cu2O crystal under resonant excitation. The detailed study of their shape and excitation spectra allowed us to interpret these bands as two-electron transitions in the non-equilibrium system of interacting ortho- and para-excitons. The schematics of energy spectrum and quantum transitions for this system are suggested. The influence of exciton-exciton scattering is under consideration. (C) 2000 Elsevier Science B.V. All rights
