The nonlocal electrical resistance of a single heterojunction of a special shape in a quantizing magnetic field has been studied experimentally. Comparison of the experimental results with theoretical predictions for filling factors close to / = 1.5 reveals the temperature dependence of the frequency of transitions between quantum levels. The experimental results are explained in terms of an electron-phonon scattering accompanied by a spin flip at the boundaries of the sample.
