Oscillator strengths, Lande g values, and hyperfine structure for 3d(4) J=0 -> 3d(3) 4p J=1 transitions in Fe v - art. no. 032501

摘要

Relativistic configuration-interaction (RCI) calculations with similar to 15 000 vectors have been done for f values, Lande g values, and hyperfine structure constants for Fe v. There is at least a factor of 2 improvement over our earlier achievable accuracies (Nb II). The 21 largest f values (>0.01) have an average length-velocity gauge difference of 6.7%, and the average error in the energy differences between adjacent levels is 213 (180) cm(-1) for even- (odd-) parity levels. We find significant f value differences as compared to recent values from Breit-Pauli R-matrix calculations, and, to a lesser extent, as compared to older semiempirical f values. Oscillator strengths to three nearly degenerate odd-parity levels are sensitive to errors smaller than 200 cm(-1), but the sum is conserved, as expected. [References: 27]
