Abstract
The energy and line shape of the 3P-1S transition in pionic hydrogen h ave been measured with a reflecting crystal spectrometer combined with a cyclotron trap and Charge Coupled Devices (CCDs). The instrumental resolution was 0.7 eV (FWHM) at 2.9 keV. Results for the strong intera ction energy shift and broadening of the ground state and the correspo nding pi N s-wave scattering lengths will be presented soon.
