Abstract
By measuring the cyclotron frequency ratios of to and to , and using as a mass reference, we obtain new atomic masses for and T. Our results are and , where the uncertainty includes an uncertainty of 0.12 nu in the mass reference. Allowing for cancellation of common systematic errors, we find the value for tritium decay to be . This allows an improved test of systematics in measurements of tritium decay that set limits on neutrino mass.
