Fragmentation ofO16projectiles at 100 MeV per nucleon

Energy and angular distributions of heavy (Z≥4) projectilelike residues of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ have been measured at 100 MeV/nucleon with better than unit A and Z resolution. Global fits to the isotopic distributions show close correspondence to the relativistic results. Closer examination reveals angle dependent damping of the fragmentation peak. The dependence of this damping upon the target mass gives evidence that the scattering outside the grazing angle is to positive angles.
