Abstract: (APS)
A comparative study of the fragmentation of He4, C12, N14, and O16 nuclei, E=2.1 GeV/nucleon, has been made by using nuclear emulsion detectors. The interaction mean-free paths (cm) for these nuclei in emulsion are 21.8 ± 0.7, 13.8 ± 0.5, 13.1 ± 0.5, and 13.0 ± 0.5, respectively. These data are discussed in terms of optical models and geometrical theories. Fragmentation reactions initiated by C12, N14, and O16 projectiles that exhibit no target excitation, i.e., that possess no low energy particle emission. are selected for special study of projectile fragmentation. The projected angular distributions of Z=1 and 2 secondaries from these interactions are reported, as are the prong-number and charge-multiplicity distributions. The angular distributions are independent of the projectile and exhibit features of limiting fragmentation.
