We have investigated equilibrium tunneling between disordered two-dimensional electron systems at temperature below 0.3 K and in a wide range of magnetic field normal to the electron layers. Observed transformation of a narrow conductance peak of about I mV width at zero bias into the narrow dip with magnetic field is discussed in the frame of many-electron interaction effects in tunnel phenomena.
