Abstract
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.
