Doppler-tuned laser spectroscopy has been applied to a foil-stripped 1 MeV/u silicon ion beam to measure the 1s2s 1 S0-1s2p 3 P1 intercombination interval in 28Si 12+. To obtain sufficient transition probability the Si 12+ beam was merged co-linearly with over 2 kW of continuous-wave laser light at 1319 nm inside an ultra-high finesse build-up cavity. The measurement differentiates between current theories for the n = 2 levels of helium-like ions.
