Notes: "The optimal ionization scheme of {714 nm|784 nm|993 nm(decay)|615 nm|615 nm} was found to provide an enhancement factor of 3.8 with respect to surface ionization in a tantalum hot cavity heated to 2060⁰C. This ionization scheme includes five atomic transitions in the process of exciting to 49 193.7 cm-1. It is the first time that optical pumping has been employed in a hot cavity RILIS ionization scheme."
