Sul decadimento beta dell’89Sr

  • Published:
Il Nuovo Cimento (1955-1965)

Riassunto

Si descrive un’esperienza diretta a individuare la forma specifica dell’interazione che regola il decadimento β dello89Sr, il cui spettro è « unico primo proibito ». I risultati, ottenuti mediante misure di correlazione angolare « elettrone-neutrino », indicano che l’interazione predominante è del tipo « vettore assiale », non escludendo tuttavia un possibile contributo della interazione di tipo « tensore » in misura non superiore al 26%.

Summary

An experiment for the determination of the specific shape of the interaction which controls the β-decay of89Sr, whose spectrum is « unique first forbidden », is described. The results, obtained using angular correlation « electron-neutrino » measurements, show that the prevailing interaction is of the « axial vector » kind, without excluding, however, a possible contribution from the interaction of « tensor » kind not greater than 26%.
