Abstract
The conductance of a ballistic quantum channel with a constriction in a quantizing magnetic field is analyzed in the case of scattering by a n isolated impurity in the channel. The transmission coefficient and t he conductance are derived for this microstructure. The parameters of a Breit-Wigner resonance and oscillations in the transmission coeffici ent are analyzed.
