摘要
The nuclear recoil effect to the g factor of boron-like ions is investigated. The one-photon-exchange correction to the nuclear recoil effect is calculated in the non-relativistic approximation for the nuclear recoil operator and in the Breit approximation for the interelectronic-interaction operator. The screening potential is employed to estimate the higher-order contributions. The updated g-factor values are presented for the ground P-2(1/2) and first excited P-2(3/2) states of B-like argon Ar-40(13+), which are presently being measured by the ARTEMIS group at GSI.
