Accurate values of the Lamb shift can be derived from measurements of the anisotropy in the angular distribution of the radiation accompanying the electric field induced 2s-1s transition of hydrogen. Calculations of the anisotropy, including relativistic and hyperfine structure corrections, are presented for the hydrogenic ions up to S/sup 15+/. The data enable the calculation of the Lamb shift from a measured value of the anisotropy. (AIP)
