Photoionisation of Ca${}^{+}$ ions in the valence-energy region 20$\sim$eV~--~56$\sim$eV : experiment and theory

A Mueller, S Schippers, R A Phaneuf +8

Relative cross sections for the valence shell photoionisation (PI) of ${}^2\mathrm{S}$ ground level and ${}^2\mathrm{D}$ metastable Ca${}^{+}$ ions were measured with high energy resolution by usi…
