Abstract:
The list presents electron collision strengths for the forbidden
transitions between the fifteen lowest levels of the doubly-ionized
cobalt, Co2+, as a function of the electron energy, in an
intermediate coupling scheme using the Breit-Pauli relativistic terms
as implemented in an R-matrix atomic scattering code. An atomic target
for the R-matrix scattering defined by 36 atomic terms is used in
these calculations. The data are particularly useful for analyzing the
thermodynamic conditions of supernova ejecta.
Description:
The data set consists of 105 files which are labeled as
'OMEGAmn_CoIII.dat' where m=1,2,...,14 and n=2,3,...,15 with m<n.
The indices m and n refer to the level index as given in the table
below. In each file the first column represents the electron energy in
Rydberg and the second column represents the collision strength for
the transition between the indicated levels.
