Description

When fragments of 1.85A-GeV 40Ar projectiles are observed in a CR-39 etched track detector, anomalously short mean free paths of secondary nuclei with 11> or =Z> or =17 are found within the first 2 cm after their production, at approx.3 standard deviations. This confirms the previous reports of this ''anomalon'' effect in nuclear emulsion. The data can be fitted by the hypothesis that approx.3.6% of the secondaries have a mean free path of approx.1.0 cm and infinite lifetime
