Summary
An event is described in which a χ-meson decays at rest to three charged particles, two of which are elections. Details of the measurements are given and are consistent with the interpretation of a χ-meson decay involving a π0-meson which undergoes anomalous decay to two electrons and a photon.
Riassunto
Si descrive un evento in cui un mesone χ decade a riposo in tre particelle cariche, due delle quali sono elettroni. Si danno dettagh delle misure che sono compatibili con l’interpretazione del decadimento di un mesone χ in cui si formi un mesone π0 che a sua volta soggiace a un decadimento anomalo in due elettroni e un fotone.
