Abstract
The bend resistance in narrow cross junctions has been investigated in the fractional quantum Hall regime. Dips in the resistance due to the ballistic transmission of composite fermions have been observed near nu=1/2 and 1/4. The temperature dependence of the dips is strong refle cting the small Fermi energy of the composite fermions.
