Abstract
Two new bands were observed in luminescence spectrum of high-purity Cu2O cr
ystal under resonant excitation. The detailed study of their shape and exci
tation spectra allowed us to interpret these bands as two-electron transiti
ons in the non-equilibrium system of interacting ortho- and para-excitons.
The schematics of energy spectrum and quantum transitions for this system a
re suggested. The influence of exciton-exciton scattering is under consider
