Abstract

Total cross sections have been measured for protons, deuterons, alphas, and 12C on hydrogen, deuterium, helium, and carbon targets at 1.55 and 2.89 GeV/c/nucleon using the ''good geometry'' transmission method. In addition, the inelastic cross sections and elastic slope parameters were measured for reactions initiated by deuterons, alphas, and 12C. The factorization relation sigmaT(AA) = σT(AB)2σT(BB) is violated for some of these reactions. The results generally agree with Glauber theory predictions except in their detailed energy behavior. It is found that sigmaT approximately equal to 144 (ATsup 1/3 + AP1/3 - 1.48)2 and σIN approximately equal to 78 (AT1/3 + AP1/3 - 1.25)2, where AT(AP) is the atomic mass number of the target (projectile) and the cross sections are given in mb.
