Abstract

An 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, (1s2p_3/2) ³P₂ (M1 and M2 transitions, respectively) and for the quasidegenerate states (1s2p) ¹P₁, (1s2p) ³P₁ (E1 transitions) decaying to the ground state (1s1s) ¹S₀. Two-electron ions with nuclear-charge numbers Z=10--92 are considered. The line profile approach is employed for the description of the process in multicharged ions within the framework of QED.
