Azimuthal correlations between coincident fission fragments and {alpha} particles were measured for the reactions {sup 36}Ar+{sup 238}U at {ital E}/{ital A}=20 and 35 MeV and {sup 14}N+{sup 238}U at {ital E}/{ital A}=50 MeV. At all energies, coplanar emission is enhanced. The azimuthal distributions for fission fragments and {alpha} particles are decoupled using a simple parametrization. Both azimuthal distributions are highly anisotropic at lower incident energies; these anisotropies decrease with energy. At the highest incident energies, energetic {alpha} particles emitted at large transverse momenta appear to be more suited than fission fragments to tag the orientation of the entrance channel reaction plane.
