Abstract :
[en] A new set of oscillator strengths and transition probabilities is reported for 92 radiative transitions of nine-times ionized xenon, Xe X, in the extreme ultraviolet region from 110 to 164 Å. They have been obtained by two different theoretical approaches, i.e. the pseudo-relativistic Hartree-Fock (HFR) and the fully relativistic multiconfiguration Dirac-Hartree-Fock (MCDHF) methods, which allowed us to estimate the precision of the final results. The eigenvector compositions are also given for the first time for all the experimentally known energy levels in Xe X. © 2019
