Strauch, F. Amaro, D. Anagnostopoulos, P. Bühler, D. Covita, H. Gorke, D. Gotta, A. Gruber, A. Hirtl, P. Indelicato, E. Le Bigot, M. Nekipelov, J. dos Santos, Ph. Schmid, S. Schlesser, L. Simons, M. Trassinelli, J. Veloso, J. Zmeskal] The strong-interaction shift ε 1s πD and broadening Γ 1s πD in pionic deuterium have been determined in a high statistics study of the πD(3p-1s) X-ray transition using a high-resolution crystal spectrometer. The pionic deuterium shift will provide constraints for the pion-nucleon isospin scattering lengths extracted from measurements of shift and broadening in pionic hydrogen. The hadronic broadening is related to pion absorption and production at threshold. The results are ε 1s πD = (−2356 ± 31) meV (repulsive) and Γ 1s πD meV yielding for the complex πD scattering length a πD = [−(24.99±0.33)+i(6.22 −0.26 +0.12 )] × 10−3 m π −1 . From the imaginary part, the threshold parameter for pion production is obtained to be α = (251 −11 +5 ) μb. This allows, in addition, and by using results from pion absorption in 3He at threshold, the determination of the effective couplings g 0 and g 1 for s-wave pion absorption on isoscalar and isovector NN pairs.
