The lifetime of the metastable 5d ^2D 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 T D 5/2 = 26.4(1.7)s is obtained through extrapolation to zero residual gas pressure.
