Abstract: | An investigation is made of the self-interaction of whistler waves (whistlers) involving the formation of waveguide channels
in a collisional magnetoactive plasma as a result of its additional ionization by the field of the propagating wave. Simplified
equations are derived to describe the behavior of the whistler field in a channel of enhanced plasma density in the presence
of electron collisions. Self-consistent distributions of the field and the plasma corresponding to steady-state ionization
self-channeling of whistlers are obtained by numerically solving the equations for the field together with balance equations
for the electron density and energy. Our estimates indicate that this effect can be observed under laboratory conditions.
