On the decay interactions of neutral Ke3 and Kμ3

SummaryThe decay interactions of the processes K0→ e+ν+πc and K0→ μ+ν+π0 are investigated. Under the assumption that these processes occur through the weak Fermi interaction the analysis has been performed about the energy spectra and angular correlations of charged secondaries in order to obtain some information about the decay interactions.RiassuntoSi esaminano le interazioni di decadimento dei proeessi K0→ e+ ν + πc e K0→μ+ν+πc. Facendo l’ipotesi che questi processi avvengano tramite Finterazione di Fermi debole, l’analisi è stata portata sugli spettri energetici e le correlazioni angolari dei secondari carichi onde ottenere informazioni sulle interazioni di decadimento.

Some features of the electron energy spectrum in the Ke3 decay process

It is shown that there exist some characteristic features in the theoretical energy spectrum of the electrons in K/sub e3/ decay, and the experimental analysis of these simple features seems to be easier than the investigation for the correlation with the pion energy. The electron-pion energy correlation function is given. The ratio of high-energy secondary electrons to lowenergy electrons is investigated. (W.D.M.)
