Relativistic manybody calculations of multipole (E1, M1, E2, M2, E3, and M3) transition wavelengths and rates between 3l^{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 ^{2}3p ^{6}3d ^{9}4l, 3s ^{2}3p ^{5}3d ^{10}4l, and 3s3p ^{6}3d ^{10}4l and the ground 3s ^{2}3p ^{6}3d ^{10} 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 ^{2}2s ^{2}2p ^{6}3s ^{2}3p ^{6}3d ^{10} 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 possible multipole (E1, M1, E2, M2, E3, and M3) transitions between the excited 3s ^{2}3p ^{6}3d ^{9}4l, 3s ^{2}3p ^{5}3d ^{10}4l, and 3s3p ^{6}3d ^{10}4l states and the ground 3s ^{2}3p ^{6}3d ^{10} state in Nilike ions. Trends of the line strengths for the 76 multipole transitions and oscillator strengths for the 13 E1 transitions as function of Z are illustrated graphically. The Zdependence of the energy splitting for all triplet terms of the 3s ^{2}3p ^{6}3d ^{9}4l, 3s ^{2}3p ^{5}3d ^{10}4l, and 3s3p ^{6}3d ^{10}4l configurations are shown in the range of Z = 30100.
