Abstract: Tunnelling between two-dimensional electron systems has been studied in themagnetic field perpendicular to the systems planes. The satellite conductancepeaks of the main resonance have been observed due to the electron tunnellingassisted by the elastic scattering on impurities in the barrier layer. Thesepeaks are shown to shift to the higher voltage due to the Coulomb pseudogap inthe intermediate fields. In the high magnetic fields the pseudogap shift isdisappeared.
