Abstract
We report calculations of many-electron quantum electrodynamic (QED) effects for the 4s2 1S0–4s4p 1P1 transition in high-Z Zn-like ions with Z = 70, 74, 76, 79, 82, 83, 90, and 92. When combined with earlier relativistic many-body perturbation theory (RMBPT) calculations, good agreement is found with recent measurements, Trabert et al. (Phys. Rev. A, 70, 032506 (2004)) at the level of 1–2 experimental standard deviations. We discuss the additional QED and RMBPT calculations that it would be desirable to perform to confirm this level of agreement.PACS Nos.: 31.30.Jv, 32.30.Rj, 31.25.–v, 31.15.Ar
