Abstract:
Large-scale calculations of atomic structures and radiative properties
have been carried out for singly, doubly- and trebly ionized cerium.
For this purpose, the purely relativistic multiconfiguration
Dirac-Hartree-Fock (MCDHF) method was used, taking into account the
effects of valence-valence and core-valence electronic correlations in
detail. The results obtained were then used to calculate the expansion
opacities characterizing the kilonovae observed as a result of neutron
star mergers. Comparisons with previously published experimental and
theoretical studies have shown that the results presented in this work
are the most complete currently available, in terms of quantity and
quality, concerning the atomic data and monochromatic opacities for
CeII, CeIII and CeIV ions.
Description:
Multiconfiguration Dirac-Hartree-Fock (MCDHF) wavelengths in vacuum,
level energies, parities and total angular quantum numbers for the
lower and upper levels of the transitions, weighted oscillator
strengths in logarithmic scale (loggf), weighted transition
probabilities (gA) for E1 transitions in CeII, CeIII and CeIV.
