Abstract
We present a measurement of the branching fractions for decay from the long-lived level in . The branching fraction for decay into the ground state was found to be . We also report an improved measurement of the lifetime, s. Together these measurements provide an experimental determination of transition rates for decay out of the level. The low ( Torr) pressure in the ion trap in which these measurements were made simplified data acquisition and analysis. Comparison of the experimental results with theoretical predictions of the transition rates shows good agreement.
