Anomalous magnetic moment of a bound electron
We study binding corrections to the gyromagnetic factor ge of an electron in hydrogen-like ions. We argue that the leading order binding effects in radiative corrections ∆grad are universal to all orders in α/π and the complete result reads ∆grad = (gfree − 2) · [1 + (Zα) 2/6] + O ( α π · (Zα)4 ) . The theoretical uncertainty in the prediction for the experimentally interesting carbon ion is de...
متن کاملRecoil correction to the magnetic moment of a bound electron
The effect of a finite nuclear mass on the magnetic moment of the electron bound in the ground state of a hydrogen-like ion is analyzed. Using the exact in Zα expression for the recoil shift of the energy, I calculate the order (Zα)4m/M correction to the electron gyromagnetic ratio. The theoretical uncertainty in the prediction for the experimentally interesting carbon ion is decreased to the l...
متن کاملHigh-accuracy measurement of the magnetic moment anomaly of the electron bound in hydrogenlike carbon.
We present a new experimental value for the magnetic moment of the electron bound in hydrogenlike carbon (12C5+): g(exp) = 2.001 041 596 (5). This is the most precise determination of an atomic g(J) factor so far. The experiment was carried out on a single 12C5+ ion stored in a Penning trap. The high accuracy was made possible by spatially separating the induction of spin flips and the analysis...
متن کاملTwo Component Theory and Electron Magnetic Moment
The two-component formulation of quantum electrodynamics is studied. The relation with the usual Dirac formulation is exhibited, and the Feynman rules for the two-component form of the theory are presented in terms of familiar objects. The transformation from the Dirac theory to the two-component theory is quite amusing, involving Faddeev-Popov ghost loops of a fermion type with bose statistics...
متن کاملOn The Electron Magnetic Moment Anomaly
It can be shown that the difference between the experimental value of the electron magnetic moment and that of the Bohr magneton is due to the magnetic drift of the electron's carrying energy induced at the hydrogen ground state gyroradius, corresponding to the electron being forced to move on a closed orbit about the nucleus in an isolated hydrogen atom.
