Abstract: Spectroscopy of helium is discussed in the context of methods to determine the fine structure constant a. Resonances corresponding to the fine structure separation are observed in the coherent excitation of a He-4 metastable beam by two laser fields. A quantitative analysis of the Lineshapes is performed for the three level model (
