Angular distributions are reported for /sup 37/Ar and /sup 127/Xe produced by the interaction of 8-GeV /sup 20/Ne and 25-GeV /sup 12/C ions with Au. A shift from a forward to a sideward peaked distribution is observed for /sup 37/Ar, similar to that known to occur for incident protons over the same energy interval. Analysis of these data and those for Z = 8 fragments indicate that reactions leading to heavy fragment emission become more peripheral as bombarding energies increase. A mechanistic analysis is presented which explores the ranges of applicability of several models and the reliability of their predictions to fragmentation reactions induced by both energetic heavy ions and protons.
