Excitation energies, polarizabilities, multipole transition rates, and lifetimes in Th IV
U. I. Safronova, W. R. Johnson, M. S. Safronova
Excitation energies of the ns_{1/2} (n=7-10), np_j (n=7-9), nd_j (n=6-8), nf_{j} (n=5-7), and ng_{j} (n=5-6) states in Th IV are evaluated. First-, second-, third-, and all-order C…
Third-order many-body perturbation theory calculations for the beryllium and magnesium isoelectronic sequences
H. C. Ho, W. R. Johnson, S. A. Blundell +1
Relativistic third-order MBPT is applied to obtain energies of ions with two valence electrons in the no virtual-pair approximation (NVPA). A total of 302 third-order Goldstone dia…
Relativistic many-body calculations of the Stark-induced amplitude of the 6P1/2 -7P1/2 transition in thallium
M. S. Safronova, W. R. Johnson. U. I. Safronova, T. E. Cowan
Stark-induced amplitudes for the 6P1/2 - 7P1/2 transition in Tl I are calculated using the relativistic SD approximation in which single and double excitations of Dirac-Hartree-Foc…
