Abstract
The Ca I absorption spectrum has been photographed between 10 and 120 angstrom for the first time. At least seven discrete features-all attributable to excitation of the 2p subshell - have been observed. Identifications are made by comparison with Hartree-Fock calculations. The Hartree-Fock results also support an explanation of the irregular quantum defects and remarkable breadths of the lines assigned to the 2p $\rightarrow $ 3d transition.
