Relativistic manybody calculations of multipole (E1, M1, E2, M2, E3, and M3) transition wavelengths and rates between 3l{sup 1}4l' excited and ground states in nickellike ions
Abstract
Wavelengths, transition rates, and line strengths are calculated for the 76 possible multipole (E1, M1, E2, M2, E3, and M3) transitions between the excited 3s{sup 2}3p{sup 6}3d{sup 9}4l, 3s{sup 2}3p{sup 5}3d{sup 1}4l, and 3s3p{sup 6}3d{sup 1}4l and the ground 3s{sup 2}3p{sup 6}3d{sup 1} states in Nilike ions with the nuclear charges ranging from Z = 30 to 100. The relativistic manybody perturbation theory (RMBPT), including the Breit interaction, is used to evaluate energies and transition rates for multipole transitions in holeparticle systems. This method is based on relativistic manybody perturbation theory, agrees with MCDF calculations in lowestorder, includes all secondorder correlation corrections, and includes corrections from negative energy states. The calculations start from a 1s{sup 2}2s{sup 2}2p{sup 6}3s{sup 2}3p{sup 6}3d{sup 1} DiracFock potential. Firstorder perturbation theory is used to obtain intermediatecoupling coefficients, and the secondorder RMBPT is used to determine the matrix elements. The contributions from negativeenergy states are included in the secondorder E1, M1, E2, M2, E3, and M3 matrix elements. The resulting transition energies and transition rates are compared with experimental values and with results from other recent calculations. As a result, we present wavelengths and transition rates data for the selected transitions that include the 76 possiblemore »

Multipole (E1, M1, E2, M2, E3, M3) transition wavelengths and rates between 3l15l' excited and ground states in nickellike ions
A relativistic manybody method is developed to calculate energy and transition rates for multipole transitions in manyelectron ions. This method is based on relativistic manybody perturbation theory (RMBPT), agrees with MCDF calculations in lowestorder, includes all secondorder correlation corrections and includes corrections from negative energy states. Reduced matrix elements, oscillator strengths, and transition rates are calculated for electricmultipole (dipole (E1), quadrupole (E2), and octupole (E3)) and magneticmultipole (dipole (M1), quadrupole (M2), and octupole (M3)) transitions between 3l{sup 1}5l{prime} excited and ground states in Nilike ions with nuclear charges ranging from Z = 30 to 100.

Energies and E1, M1, E2, and M2 transition rates for states of the 2s{sup 2}2p{sup 3}, 2s2p{sup 4}, and 2p{sup 5} configurations in nitrogenlike ions between F III and Kr XXX
Based on relativistic wavefunctions from multiconfiguration Dirac–Hartree–Fock and configuration interaction calculations, E1, M1, E2, and M2 transition rates, weighted oscillator strengths, and lifetimes are evaluated for the states of the (1s{sup 2})2s{sup 2}2p{sup 3},2s2p{sup 4}, and 2p{sup 5} configurations in all nitrogenlike ions between F III and Kr XXX. The wavefunction expansions include valence, core–valence, and core–core correlation effects through single–double multireference expansions to increasing sets of active orbitals. The computed energies agree very well with experimental values, with differences of only 300–600 cm{sup −1} for the majority of the levels and ions in the sequence. Computed transitions rates aremore »
