  We use a quasi-Corbino sample geometry with independent contacts to different
edge states in the quantum Hall effect regime to investigate a charge
redistribution between cyclotron-split edge states at high imbalance. We also
modify Buttiker formalism by introducing local transport characteristics in it
and use this modified Buttiker picture to describe the experimental results. We
find that charge transfer between cyclotron-split edge states at high imbalance
can be described by a single parameter, which is a transferred between edge
states portion of the available for transfer part of the electrochemical
potential imbalance. This parameter is found to be independent of the
particular sample characteristics, describing fundamental properties of the
inter-edge-state scattering. From the experiment we obtain it in the dependence
on the voltage imbalance between edge states and propose a qualitative
explanation to the experimental findings.
