Experimental evaluation of the π+→π0+e++ν decay probability

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

By means of γ-γ coincidences it has been shown that the probability of positive pion β-decay does not exceed 7·10−8 of the probability of muon decay of pion. For the constant G which determines the intensity of this process in the case of vector current conservation the following evaluation has been obtained:G < 2.5G β, whereG β is the constant of weak vector β-interaction.

Riassunto

A mezzo di coincidenze γ-γ si è dimostrato che la probabilità del decadimento β del pione positivo non supera 7·10−8 volte la probabilità del decadimento del pione in un muone. Per la costanteG, che determina l’intensità di questo processo nel caso della conservazione della corrente vettoriale, si è ottenuto il seguente valore: G < 2.5Gβ, in cuiG β è la costante della interazione β vettoriale debole.

Additional information

Sometimes another process π±→ e± + ν is called a pion β-decay. It would be more correct to call it an electron mode of pion decay (1).
