Figure 5.
The photoionization cross-section is presented on a linear scale against photon energy in eV above 261.2 eV. The solid black line represents our current DARC3 model convoluted at 140 meV FWHM and the dashed black line is the contribution to the cross-section from valence shell photoionization of the 3s and 3p. The grey circles are experimental values of Blancard et al. (2012) for the single ionization channel and pink circles represent the total contribution. Each 2p53s23p5 threshold is represented by an asterisk.
