【 摘 要 】

We consider ballistic transport of composite fermions in a realistic microconstriction. An unambiguous signature of such transport is revealed: the linear conductance increases with increasing magnetic field near filling factor 1/2 and then drops abruptly in a narrow magnetic-field interval.
