Čerenkov and isotropic radiations from single μ-mesons in air

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The Čerenkov effect has been used to detect single μ-mesons in 6 m of air at atmospheric pressure. The yield of light and rate of occurrence of events is consistent with the classical theory of the effect. A separate experiment revealed that, in the absence of Čerenkov radiation, the production of light associated with ionization is <10−2 of that of Čerenkov radiation, or <4·10−6 of the rate of loss of energy by ionization for relativistic μ-mesons.

Riassunto

Si è ricorso all’effetto Čerenkov per rivelare singoli mesoni μ in 6 m d’aria a pressione atmosferica. La quantità di luce emessa e la frequenza degli eventi sono in accordo con la teoria classica dell’effetto. Un esperimento apposito ha mostrato che, in assenza di radiazione Čerenkov, la produzione di luce associata a ionizzazione è <10−2 di quella della radiazione Čerenkov, o <4·10−6 della perdita di energia per ionizzazione, per i mesoni μ relativistici.
