Summary

Results on the parity-nonconserving alpha width Λ α PNC of the (Jπ,T=0+, 1)E x =4.753 MeV level of18F are reported. This level is tentatively fed by the14N(α, γ)18F reaction and the absence of de-excitation γ-ray allows us to set an upper limit of Λ α PNC ⩽1.2·10−5 eV.

Riassunto

Si riportano i risultati dell’ampiezza di alfa Λ α PNC che non conserva la parità del livello (Jπ,T=0+, 1)E x =4.753 MeV di18F. Si tenta di alimentare quel livello mediante la reazione14N(α, γ)18F e l’assenza di un raggio gamma di diseccitazione permette di fissare un limite superiore di Λ α PNC ⩽1.2·10−5 eV.
