    "abstract": "The v^2/c^2 expansion of the Dirac equation with external potentials is\nreexamined. A complete, gauge invariant form of the expansion to order (1/c)^2\nis established which contains two additional terms, as compared to various\nversions existing in the literature. It is shown that the additional terms\ndescribe relativistic decrease of the electron spin magnetic moment with\nincreasing electron energy.",
