The strong-interaction effects both in pionic hydrogen and deuterium atoms have been re-determined with improved precision. The hadronic shift and width in pionic hydrogen together with the hadronic shift in pionic deuterium constitute a one-fold con

Line shape of the μ H(3 p - 1 s ) transition

Autor: Covita, D., Anagnostopoulos, D., Gorke, H., Gotta, D., Gruber, A., Hirtl, A., Ishiwatari, T., Indelicato, P., Le Bigot, E., Nekipelov, M., dos Santos, J., Schmid, Ph, Simons, L., Trassinelli, M., Veloso, J., Zmeskal, J.

The line shape of the (3p − 1s) X-ray transition in muonic hydrogen was measured for the first time with a high-resolution crystal spectrometer. The assumption of a statistical population of the hyperfine levels was directly confirmed by experiment

High-precision measurements of the proton radius from laser spectroscopy of muonic hydrogen demonstrated up to six standard deviations smaller values than obtained from electron-proton scattering and hydrogen spectroscopy. The status of this discrepa
