Angular distributions of deep spallation and fragmentation products of the interaction of 800 GeV protons with lanthanum, terbium, and lutetium have been measured. The angular distributions can be characterized by two parameters, A/sub 1/ and A/sub 2/, which determine the asymmetry and the anisotropy, respectively. For products with Aapprox. >30, values of A/sub 1/ and A/sub 2/ derived from high-energy proton data for targets ranging from silver to uranium are found to scale with the mass difference between target and product.
