Abstract:
This work reports radiative transition rates and electron impact
excitation rate coefficients for levels of the n=3, 4, 5, 6, 7, 8
configurations of CaII.
The radiative data were computed using the Thomas-Fermi-Dirac central
potential method in the frozen core approximation and includes the
polarization interaction between the valence electron and the core
using a model potential. This method allows for configuration
interactions (CI) and relativistic effects in the Breit-Pauli
formalism. Collision strengths in LS-coupling were calculated in the
close coupling approximation with the R-matrix method. Then, fine
structure collision strengths were obtained by means of the
intermediate-coupling frame transformation (ICFT) method which
accounts for spin-orbit coupling effects.
