Configuration-interaction plus many-body-perturbation-theory calculations of Si i transition probabilities, oscillator strengths, and lifetimes

CALCULATIONS OF OSCILLATOR STRENGTHS AND LIFETIMES OF CuI, AgI AND AuI USING COULOMB APPROXIMATION

Oscillator strengths and lifetimes of all energy levels of CuI, Agl and AuI were calculated using the Coulomb approximation (for The first time), and then compared with available data

Semi-empirical studies of atomic transition probabilities, oscillator strengths and radiative lifetimes in Hf II

Over the past few years, laser induced fluorescence and Fourier Transform techniques have been applied to measure radiative lifetimes and branching fractions in Hf II in order to derive oscillator strengths and transition probabilities. In the present work, we propose to compare for the first time these experimental data to computed values obtained by two different semi-empirical approaches, re...

Relativistic many-body calculations of electric-dipole lifetimes, transition rates, and oscillator strengths for n = 3 states in Al-like ions

Transition rates, oscillator strengths, and line strengths are calculated for electric-dipole(E1) transitions between even-parity 3s3p, 3s3d, 3p3d, 3d3s and 3d states and odd-parity3s3p, 3p, 3s3p3d, and 3d3p states in Al-like ions with the nuclear charges ranging fromZ = 15 to 100. Relativistic many-body perturbation theory (MBPT), including the Breitinteraction, is used to eval...

Relativistic many-body calculations of excitation energies and oscillator strengths in Ni-like ions

Excitation energies for 3l-4l8 particle-hole states of Ni-like ions are determined to second order in relativistic many body perturbation theory. The calculations start from a closed-shell Dirac-Fock potential, and include second-order Coulomb and Breit-Coulomb interactions. Retarded electric-dipole matrix elements ~in length and velocity forms! are calculated in second order for transitions fr...
