Direct Measurement of theC12+C12Reaction Cross Section between 10 and 83 MeV/Nucleon

Abstract
The first results of direct measurements of heavy-ion reaction cross sections, σR, with use of the beam attenuation method are reported. For the C12 + C12 system σR was measured at three incident energies, 112, 360, and 996 MeV. The data show deviations from the geometrical reaction cross section and agree with recent theoretical predictions based on Glauber theory.
