The transverse momenta (px,py) of projectile fragments produced by 1.0A GeV 197Au nuclei incident on Au and C targets have been measured. The medium and heavy fragments have px and py distributions, which are wider than predicted by models. For the Au target the widths of the distributions are significantly larger than those for C, particularly for the heavy fragments. The C distributions show a different gross structure, which may be due to the target-projectile size difference.
