Deuterium Lamb shift via quenching-radiation anisotropy measurements

1978 Physical review. A, General physics  
The Lamb shift of a hydrogenic ion can be deduced from the anisotropy in the angular distribution of the. 2$1/2-1s, &, electric field quenching radiation. The accuracy of our previous. anisotropy measurement for deuterium is improved to about + 150 ppm. The derived Lamb shift is (1059.36+0.16) MHz. The sources. of error are carefully analyzed and the prospects for further improvements in the a&curacy are discussed, .
