Abstract
We discuss the behavior of the ballistic conductance of a quasi-one-di mensional microstructure in a parallel magnetic field when there is el ectron scattering by a single point impurity inside a channel. An exac t analytic formula for the conductance is derived for a model in which the confinement potential is a parabolic well. We show that the condu ctance curve consists of quantization steps with sharp resonance peaks near the thresholds. Finally, we find the amplitudes and halfwidths o f these peaks.
