The resonant subband-Landau-level coupling(RSLC) between the N=1 Landau level of the lowest subband and the N0 Landau level of the subbands with quantum index up to i5 of two-dimensional electron gases in GaAs/AlGaAs heterojunction was observed under relatively low magnetic field.Several intersubband energies were accurately determined. The experimental results were in good agreement with the self-consistent calculations including the depolarization shift and exciton-like effect corrections.The quantum index dependence of the level splitting due to the RSLC was discussed.
