000917190 520__ $$aThe strong-interaction effects both in pionic hydrogen and deuteriumatoms have been re-determined with improved precision. The hadronicshift and width in pionic hydrogen together with the hadronic shift in pionicdeuterium constitute a one-fold constraint for the two independent pion-nucleonscattering lengths. Furthermore, the hadronic width in pionic deuterium measuresthe transition strength of s-wave pions on an isoscalar nucleon-nucleonpair which is an independent quantity not related to the pion-nucleon scatteringlengths. The experiment was performed at the Paul Scherrer Institute bystopping a high-intensity low-energy pion beam in gaseous targets using thecyclotron trap. The X-rays emitted by the H and D atoms were analysedwith a high resolution Bragg spectrometer equipped with spherically bent crystals.The pion-nucleon scattering lengths and other physical quantities extractedfrom the atom data are in good agreement with the results obtained from pion-nucleonand nucleon-nucleon scattering experiments and confirm that a consistentpicture is achieved for the low-energy pion-nucleon sector with respect tothe expectations of chiral perturbation theory.
