Heckman, H H

Two independent emulsion experiments using beams of /sup 16/O and /sup 56/Fe at approximately 2 GeV/nucleon find that the reaction mean free paths of projectile fragments (PF) with Z between 3 and 26 are shorter for a few centimeters after their emission than at larger distances, or than predicted from experiments on beam nuclei. Under the assumption that there are two populations of PF, a best fit to the data is obtained when approximately 6% of the PF have an anomalously short mean free path. The anomalous property of PF persists in subsequent fragmentation reactions. 6 figures. (RWR)
