We measured the isotope shift of the MgI intercombination line 3s3p3P1-3s21S0 (λ=457 nm) for the three stable isotopes 24Mg, 25Mg and 26Mg. The measurement was performed by optical Ramsey spectroscopy (respectively saturation spectroscopy for 25Mg) on a magnesium atomic beam. The rf precision of the measurement was achieved by using optical sideband techniques for the stabilization and tuning of a dye laser relative to an ultrastable cavity.
