Abstract

Interaction mean free paths of projectile fragments emitted from relativistic Fe–C and Fe–Pb interactions were measured by means of emulsion stacks arranged at just downstream (S-stacks) and at 15 cm downstream of targets (L-stacks). There is no difference in mean free paths of fragments emitted from both target interactions, and in S- and L-stacks. The difference of mean free paths between upstream and downstream parts of stacks is also undetected by two analysing methods. The ‘Anomalon effect’ is not observed in present experiment.
