Decay of a Tau-Meson Underground

Article metrics


THE decay of heavy cosmic ray particles underground has been reported by Higashi et al. 1, and L. and M. Avan1. Higashi found a neutral V-particle in a multiplate cloud chamber at a depth of 40 metres water equivalent underground. The V-particle was produced by a shower secondary from a large interaction in the chamber. Avan, using glass-backed emulsions at a depth of 300 metres water equivalent, reported the decay of two K-mesons, one of which was produced in the glass backing of an emulsion.
