Metastable pionic helium is a hypothetical three-body atom composed of a helium nucleus, a π- occupying a Rydberg state, and an electron occupying the ground state. The PiHe collaboration is currently attempting to carry out laser spectroscopy of these atoms using the 590-MeV ring cyclotron of the Paul Scherrer Institute. We briefly describe the method by which we intend to detect the spectroscopic signal.
