Abstract

Half-lives and branching ratios for the Fermi

β

decays of

{}^{18}{Ne}

{}^{22}{Mg}

{}^{26}{Si}

, and

{}^{34}{Ar}

have been studied in experiments which employed a gas-transport system. The

ft

values for the last two are compared with the mirror decays of

{}^{26}{Al}^{m}

and

{}^{34}{Cl}

. A difference of (4.6 ± 1.7)% is observed for mass 34 and may be attributable to unexpectedly large charge-dependent mixing. Possible implications are discussed with respect to Cabibbo theory and the existence of an intermediate vector boson.
