Title:An attempt to a $\beta$ rays theory

Abstract: A quantitative theory of $\b$-rays emission is proposed in which \lcaporali neutrino\rcaporali\ is admitted; electrons and neutrinos emission from a nucleus at a $\b$ decay is treated with a procedure similar to the one followed for radiation theory to describe a light quantum emission by an excited atom. Formulae are derived for the mean life and for the distribution of the $\b$-rays continuum spectrum, which are compared with experimental data.

Keywords: Beta-decay theory
