do_coulomb_born_approx Module Subroutine

public module subroutine do_coulomb_born_approx(cfg, n_states, egrid_elec_cb, transitions_cb, xs_xcite_pcb, xs_xcite_tcb, pcb_output_directory, tcb_output_directory)

Use the Coulomb-Born approximation to get scattering cross sections for e⁻ + target. Also determines Einstein A coefficients and excited state average lifetimes within !! the radiative dipole/multipole approximation. The target charge Z is supplied and used by the routine that are called here, so various target charges can be used, including Z = 0 (neutral targets). This routine loops over the different pairs Nτ —→ N'τ'
