Abstract

An experiment to measure the strong interaction width (Γ 1s,) and shift (ε1s) of the ground state of pionic hydrogen (π-p), in order to determine the isospin separated scattering lengths (a+ and a-) with a relative accuracy of better than 10-2, has been undertaken at the Paul Scherrer Institute (PSI). This measurement is based on high-precision X-ray spectroscopy of the np → 1s transitions pionic hydrogen (π-p). A preliminary analysis of the data taken in December 2000 is presented.
