Abstract

The lifetime of the metastable 5d $^2$ D $_{5/2}$ state has been measured for a single trapped Ba $^+$ ion in a Paul trap in Ultra High Vacuum (UHV) in the 10 $^{-10}$ mbar pressure range. A total of 5046 individual periods when the ion was shelved in this state have been recorded. A preliminary value $\tau_{D_{5/2}} = 26.4(1.7)$ ~s is obtained through extrapolation to zero residual gas pressure.
