摘要：

The 3P-1S X-ray transition energy was measured in pionic hydrogen with a double focussing silicon crystal spectrometer in combination with a cyclotron trap and CCD detectors: E = 2885.98 +/- 0.17 (stat.) +/- 0.15 (syst.) eV. The corresponding strong interaction shift epsilon-1S = -7.12 +/- 0.32 eV (attractive) yields the scattering length combination 1/3 (2a1 + a3) = 0.086 +/- 0.004 m-pi-1.
