Abstract

The effects of strong interaction on the 3 → 2 X-ray transition in antiprotonic 6Li/7Li atoms have been measured at the low energy p-beam at CERN. For the shifts and widths of the levels the values ϵ2p = (−230 ± 72) eV, Γ2p = (443 ± 210) eV, and Γ3d = (0.130 ± 0.045) eV for 6Li, and ϵ2p = (−336 ± 60) eV, Γ2p = (456 ± 190) eV, and Γ3d = (0.210 ± 0.062) eV for 7Li were found. The data are compared with optical model predictions.
