Abstract

The X-ray spectrum of pionic 208Pb has been measured. The deduced values of the strong interaction monopole shift with respect to the point Coulomb energy are e0(4f) = 1.49±0.02 keV and e0(3d) = 19.4±1.2 keV. The observed s strong interaction absorption widths of this spherical nucleus are found to be G0(4f) = 1.25±0.02 keV and G0(3d) = 47.0±3.6 keV. Important in the analysis of the pionic 4f level is the intensity balance for this level, giving an additional check on the measured absorption width of the pionic 4f level. For the more peripheral 4f state the measured strong interaction shifts and widths are well explained by standard optical model calculations. The values for the 3d state, however, are not in agreement with these calculations.
