Electron scattering from the fine structure levels within the 1s22s22p2 3Pe ground state of C I

The authors have calculated cross sections for elastic and inelastic scattering from the fine structure levels within the 1s22s22p2 3Pe ground state of C I using the R-matrix method. They include the states 1s22s22p2 3Pe, 1De, 1Se in the expansion of the total wavefunction, plus 3So, 3Po and 3Do polarisation pseudostates to allow for the ground state polarisability. The fine structure energy splittings are included explicitly. The authors present collision strengths for the inelastic transitions, averaged over a Maxwellian electron velocity distribution, for electron temperatures from 7.5 to 10000 K.
