Abstract

Accurate QED calculation of transition probabilities for the low-lying two-electron configurations of multicharged ions is presented. The calculation is performed for the nondegenerate states (1s2s)3S1(1s2s) 3S1, (1s2p3/2)3P2(1s2p_{3/2}) 3P2 (M1M 1 and M2M 2 transitions, respectively) and for the quasidegenerate states (1s2p)1P1(1s2p) 1P1, (1s2p)3P1(1s2p) 3P1 (E1E 1 transitions) decaying to the ground state (1s1s)1S0(1s1s) 1S0. Two-electron ions with nuclear charge numbers Z=1092Z=10-92 are considered. The line profile approach is employed for the description of the process in multicharged ions within the framework of QED.
