Abstract
We compare total reaction cross sections found in proton and composite-projectile ( and ) collisions with , , and target nuclei at incident energies between 5 and 600 MeV/nucleon. The energy dependence of the composite-projectile values is found to be as large as or larger than for protons. A simple semiclassical analysis suggests that, at of approximately 250 MeV, composite-projectile collisions are, in effect, more transparent than proton collisions with the same target nucleus.
