Abstract : We measured the branching fractions for the decay of the 5p 2 P 1-2 state of 88 Sr + by applying a recently demonstrated photon-counting sequential method M. Ramm et al., Phys. Rev. Lett. 111, 023004 to a single ion laser-cooled in a micro fabricated surface trap. The branching fraction for the decay into the 5s 2 S 1-2 ground level was found to be p = 0.9453 +0.0007 −0.0005. This result is in good agreement with recent theoretical calculations but disagrees with previous experimental measurements, however affected by a one order of magnitude larger uncertainty. This experiment also demonstrates the reliability and the performances of ion micro trap technology in the domain of precision measurements and spectroscopy.
