Abstract
The authors report accurate measurements of 2p3/2,1/2 to 1s (Lyman- alpha 1,2) transitions in Ar17+ produced by encounters with a U66+ beam at 5.9 MeV/nucleon. The 'recoil' production mechanism eliminates the need for Doppler corrections while a wavelength accuracy of 5 p.p.m. relative to visible standards is attained through use of a transfer standard X-ray profile. This permits a 1.5% test of the 1s1/2 Lamb shift as limited by model uncertainties arising from spectator electron satellites.Keywords
