The paper examines the 1/Z expansion method in calculating the energy levels, ionization energies, and wavelengths of the resonant Rydberg states 1snp 1P1 for atoms belonging to the helium isoelectronic sequence. The interactions of the bound electrons are treated as a perturbation that results in the electron–electron Breit interaction, relativistic corrections, and quantum electrodynamic (QED) contributions. By comparing the calculated wavelengths with a number of observed wavelengths, the QED contributions to the ground state are analyzed. PACS Nos.: 31.20Di, 31.20Tz, 31.30Jv, 31.50+W

SummaryUsing sophisticated computer programs and elaborate physical models, accurate radiative and collisional atomic data of astrophysical interest have been or are being calculated. The cases treated include radiative transitions between bound states in the 2p4and 2s2p5configurations of many ions in the oxygen isoelectronic sequence, the photoionisation of the ground state of neutral iron, the electron impact excitation of the fine-structure forbidden transitions within the 3p3ground configuration of CℓIII, Ar IV and K V, and the mass-production of radiative data for ions in the oxygen and fluorine isoelectronic sequences, as part of the international Opacity Project.
