| Popis: | The measurements made on 44 charged V-events are reported and discussed. Arguments are presented to show that most of the events are not the decays of τ- or Kμ-mesons, nor are they ‘cascade’ decays. The simplest explanation of the majority of the events is that they are decays of a heavy meson into a light charged meson and two light neutral particles. From the results of other experiments the charged secondary particles are probably μ-mesons. The primary particle in one event has a mass of at least (1184±90)m e . This event is discussed in detail. On the assumption that all the events are of the same type, the mean lifetime of the primary particles is found to be greater than 2 × 10−9 sec. Attempts to distinguish a group of particles with a shorter mean lifetime have failed. Twenty-nine of the primary particles are positively charged, thirteen negatively; the signs of two particles cannot be determined. The positive excess is attributed, in the main, to a statistical fluctuation. |
