Additionally, line strengths, oscillator strengths, and radiative rates for the electric dipole

Table of electronic factors for E0 electron and electron–positron pair conversion transitions Atom. Data Nucl. Data Tables (IF 2.623) Pub Date : 20190625
J.T.H. Dowie,T. Kibédi,T.K. Eriksen,A.E. StuchberyA new tabulation of electronic factors is reported for electron conversion for elements of Z from 5 to 126 and electronic factors for electron–positron pair conversion for elements of even Z from 4 to 100. The electronic factors for electron conversion, ΩCE(E0), were calculated using a modified version of the CATAR program developed by Pauli and Raff with a relativisticHartree–Fock–Slater approach

I. Mančev, N. Milojević, Dž. BelkićCapture of a Kshell electron by bare fast ions H+, He2+ and Li3+ from multielectron atomic targets (carbon, nitrogen, oxygen, neon and argon) is theoretically studied by means of the fourbody boundarycorrected first Born approximation. In a wide impact energy interval ranging from 100 to 40 000 keV/amu, extensive tables of the obtained stateselective cross sections Qnlm are presented for each

Hicham Agueny, Jan Petter Hansen, Alain Dubois, Abdelkader Makhoute, Abdelmalek Taoutioui, Nicolas SisouratUsing a semiclassical closecoupling approach, we have calculated electron capture, excitation and ionization cross sections for collisions of fully stripped hydrogen, helium and lithium ions with atomic hydrogen in the ground state and in all excited states up to n=3. The cross sections for collision energies between 1 and 100 keV/u are given in table form. Furthermore, we provide estimates of the

Data Nucl. Data Tables (IF 2.623) Pub Date : 20190528
Sirine Ben Nasr, Dhia Elhak Salhi, Pascal Quinet, Haikel JelassiWe disclose relativistic multiconfiguration Dirac–Hartree–Fock (MCDHF) spectrum calculations for SnXLIX. Energy levels, weighted oscillator strengths, isotope shifts, hyperfine structure and Landé gJ factors are calculated for 127 odd and evenparity states as well as lifetimes and transition rates between these states. To scrutinize the accuracy of our results, we have implemented parallel calculations

M.B. Trzhaskovskaya, V.G. YarzhemskyPresented here are the photoionization cross sections and parameters of the photoelectron angular distribution for inner atomic subshells with binding energies beyond 1.5 keV in the photon energy range from 2 keV to 12 keV. The calculations are an extension of our previous paper containing the photoionization parameters for comparatively outer shells with binding energies lower than 1.5 keV (Trzhaskovskaya

Andrius PoškusThis work describes a library of shape functions and singly differential cross sections of bremsstrahlung due to interaction of the electrons with energies from 10 eV to 3 MeV with neutral atoms. The calculations have been performed using an updated version of the set of codes BREMS, which was described in a previous publication. The calculation method is based on the relativistic partialwave formulation

Second spectrum of Manganese (Mn II), Part II: Revised fine and hyperfine structure analysis of oddparity levels Atom. Data Nucl. Data Tables (IF 2.623) Pub Date : 20190319
Safa BouazzaIn the first part of this global work, we have achieved the fine and hyperfine structure (fs and hfs) parametric study of evenparity levels, which confirmed in the whole the wellfounded basis of previous analyses. Unfortunately, in the present work devoted to oddparity levels, some divergences appear. For instance, the three levels w5P3, w5P2, w5P1 located respectively at 86898, 86937 and 86961

Kanti M. AggarwalIn this paper, energy levels, radiative rates and lifetimes are reported for 11 Flike ions with 12 ≤ Z ≤ 23. Up to 198 levels (depending on the ion) have been considered which include 113 of the 2s22p5, 2s2p6, 2s22p43ℓ, 2s2p53ℓ, and 2p63ℓ configurations. The generalpurpose relativistic atomic structure package (grasp) and the flexible atomic code (fac) have been adopted for calculating the energy

Erratum to “A critical compilation of experimental data on spectral lines and energy levels of hydrogen, deuterium, and tritium” [At. Data Nucl. Data Tables 96 (2010) 586–644] Atom. Data Nucl. Data Tables (IF 2.623) Pub Date : 20181213
A. KramidaIn the critical compilation of experimental and theoretical data on the H, D, and T spectra (Kramida, 2010), there were errors in some of the hyperfine structure parameters for deuterium. These errors are corrected here.
