Nonrelativistic Calculation of the Electron g Factor
Two of the major successes of modern quantum electrodynamics can be found in the calculations of the Lamb shift and the anomalous magnetic moment of the electron. Although no other theory can claim to successfully predict these quantities, it is nevertheless of interest to note that Bethe’s approximately correct calculation of the Lamb shift was based on a nonrelativistic electron coupled to the electromagnetic field.(1) On the other hand, attempts to utilize the same model to compute g — 2 led to failure and didn’t even result in the correct signa.(2)
