A comparative study of the fragmentationof /sup 4/He, /sup 1/2C, /sup 1/4N, and /sup 1/6O 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 /sup 1/2C, /sup 1/4N, and /sup 1/6O 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.
