We present a measurement of the A dependence of kT, the out-of-plane component of the dijet transverse momentum, in dijet events produced with a real photon beam. We also present the same measurement for dijets produced from pion-nucleus collisions in our detector. Both data sets are taken at a mean s of 21 GeV in the pT range 37 GeV/c. A clear A dependence of comparable magnitude is seen in both processes. The energy dependence of the nuclear behavior is also extracted.
