The new simple theoretical model of Cooper1 for the interface exciton with an itinerant photo-excited hole is studied. The main parameter of the model is the separation d between electron and hole, which are assumed to be con ned in the two planes. By variational numerical calculation, we obtain the values of main parameters of the exciton: binding energies, effective Bohr radius, and oscillator strengths versus parameter d. Checking the applicable of the model, we find good agreement with the previous obtained results. We find also a strong dependence on the separation d and an existence of the "death region" of the exciton coursed by the hole band gap potential.
