Abstract

Results are presented from an electronic experiment to check directly the anomalous mean-free-path phenomena observed in high-energy heavy-ion collisions. The mean-free-path measurements presented are based on interactions of 1.25 × $10^{5}$ secondary fragments produced by interactions of $1.8 A$ -GeV ${}^{40}{Ar}$ in Lucite. The result is consistent with no anomalon phenomena and rules out (95% confidence limit) anomalons being more than 2% abundant if they have interaction lengths between 0.4 and 3 cm.
