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