QED calculation of transition probabilities in two-electron ions

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 $(1s2s)3S1$, $(1s2p_{3/2})3P2$ ($M1$ 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.
