The absorption spectrum of diatomic calcium between 120 and 20 nm

The vacuum ultraviolet absorption spectrum of Ca2 has been extended down to 20 nm by using the same techniques as those described by Nzohabonayo et al. [2003, Molec. Phys., 101, 2917]. All the new states observed are Rydberg states giving three new ionization limits at 13.76 eV, 17.99 eV and a third one higher than 33 eV.
