Impact-parameter representations of elastic differential cross sections for the processes ..pi../sup plus-or-minus/p, K/sup plus-or-minus/p, pp, and p-barp at incident energies from 50 GeV to 175 GeV and in the -t range 0.03--0.75 GeV/sup 2/ are presented. The meson-baryon interactions are found to be 20% more transparent than the baryon-baryon interaction, and to have an interaction radius which is 6% smaller. The increase in the p-p total cross section as a function of energy is shown to come primarily from an increase in the p-p interaction radius, while in the K/sup +/p case an increase is seen in both the central opacity and the interaction radius.
