Atomic data estimation for H and C IV transitions in strong gravitation field

The gravitational field effect on atomic data for H and C IV transitions are considered as a perturbation of initial and final energy levels. We found that this perturbation increases with the principal quantum number. Here we give several expressions for estimation of this effect and its influence on atomic data parameters. Also, the calculations of atomic data for 1s − 2p (Lyα) and 2s − 3p transitions of hydrogen atom as well as atomic data for 2s2S1/2−2p2P0 1/2,3/2 transitions of C IV (1UV) as a function of deformation of energy levels due to gravitation field and gravitational redshift are given. The gravitational field effect should be estimated and should be taken into account in calculation of atomic data for emitters in Broad Line Regions (BLRs) of Active Galactic Nuclei (AGN).
