g(j) factor of an electron bound in a hydrogenlike ion - art. no. 032510

We present a detailed theoretical evaluation far the g(j) factor of a bound electron in hydrogenlike ions up to Z=94. All quantum electrodynamical cor rections of order (alpha/pi) are evaluated in detail-and various other cont ributions to the g(j) factor are computed and listed for 61 Z. A comparison with all existing experiments is carried out and excellent agreement is fo und. The present uncertainty in our calculations is discussed. It is not po ssible to improve this precision with only minor effort since two-photon bo und-state QED terms are uncalculated up to now.
