  The modification and amplification of the gluon angular distribution produced
along with hard jets in nuclear collisions is computed. We consider the limit
of a thin quark-gluon plasma, where the number of rescatterings of the jet and
gluons is small. The focus is on jet quenching associated with the formation of
highly off-shell partons in hard scattering events involving nuclei. The
interference between the initial hard radiation amplitude, the multiple induced
Gunion-Bertsch radiation amplitudes, and gluon rescattering amplitudes leads to
an angular distribution that differs considerably from both the standard DGLAP
evolution and from the classical limit parton cascading. The cases of a single
and double rescattering are considered in detail, and a systematic method to
compute all matrix elements for the general case is developed. A simple power
law scaling of the angular distribution with increasing number of rescatterings
is found and used for estimates of the fractional energy loss as a function of
the plasma thickness.
