QED theory of transition probabilities and line profiles in highly-charged ions
A rigorous QED theory of the spectral line profiles is applied to transition
probabilities in few-electron highly charged ions. Interelectron interaction
corrections are included as well as radiative corrections. Parity nonconserving
(PNC) amplitudes with effective weak interactions between the electrons and
nucleus are also considered. QED and interelectron interaction corrections to
the PNC amplitudes are derived
Extension of the sum rule for the transition rates between multiplets to the multiphoton case
The sum rule for the transition rates between the components of two
multiplets, known for the one-photon transitions, is extended to the
multiphoton transitions in hydrogen and hydrogen-like ions. As an example the
transitions 3p-2p, 4p-3p and 4d-3d are considered. The numerical results are
compared with previous calculations.Comment: 10 pages, 4 table
