| Abstract | A recent laser spectroscopy experiment of three-body pionic helium atoms which was carried out using the 590 MeV ring cyclotron facility of the Paul Scherrer Institute (PSI) is briefly reviewed. The charged pion mass may be precisely determined by measuring the transition frequency of the pionic atom and comparing the results with quantum electrodynamics (QED) calculations. The experimental methods used to detect the atomic resonance are described. |
