Abstract
We study binding corrections to the gyromagnetic factor g_e of an electron in hydrogen-like ions. We argue that the leading order binding effects in radiative corrections Delta g_rad are universal to all orders in alpha/pi and the complete result reads Delta g_rad = (g_free - 2) [1+(Z alpha)^2/6] + O[alpha/pi (Zalpha)^4]. The theoretical uncertainty in the prediction for the experimentally interesting carbon ion is decreased by a factor of about 3.
