Weighted oscillator strengths for the Xe IV spectrum

Relativistic Hartree-Fock and Dirac-Fock atomic structure and radiative parameter calculations in nine-times ionized xenon (Xe X)

“…E-mail address: pascal.quinet@umons.ac.be (P. Quinet). and infrared regions [5][6][7][8][9][10][11] . In these investigations, time-resolved experiments and relativistic Hartree-Fock calculations were also performed to obtain radiative lifetimes and transition probabilities.…”

New Energy Levels and Transitions of 5s25p2 (6d+7s) Configurations in Xe IV

“…We also calculated the weighted transition probability rate gA, where g is the statistical weight 2J+1 of the upper level. We presented gA values obtained from the four methods studied: With and without optimized parameters obtained from least-squares calculations, and with and without core polarization effects for wavefunctions and reduced matrix elements calculations.In these methods, we used the same configuration sets as in [15], that is, 5s 2 5p 3 , 5 2 5p 2 (4f+6p), 5s 5p 3 5d, 5p 5 and 5s5p 4 , 5s 2 5p 2 (6s+7s+5d+6d) configurations for odd and even parities, respectively. Table 4 shows the result of least squares adjustment for even parity levels, where 6d and 7s configurations are included.All single configuration parameters, the R k integrals for 5s5p 4 -5s 2 5p 2 6s, 5s5p 4 -5s 2 5p 2 5d, 5s 2 5p 2 6s -5s 2 5p 2 5d interactions, and the R 1 (5p,5d;6d,5p)of the 5s 2 5p 2 5d -5s 2 5p 2 6d interaction were left free during the final calculation.…”

“…Saloman [11] published a revised compilation of energy levels and observed spectral lines of all ionization stages of Xe, referring to studies published to date [12][13][14][15][16]. Light sources include direct-current hollow cathode discharge, theta-pinch discharge, and pulsed capillary discharge.…”

“…More recently the study by Raineri et al [15] reported the weighted oscillator strengths and cancellation factor (CF), calculated from fitted values of the energy parameters of all 769 dipole electric lines belonging to the Xe IV spectrum reported in the compilation [11], including 49 new classified lines.…”
