The high-dispersion absorption spectrum of Ca I is reported for the 1430–1340 Å region. Observations include transitions from 4s21S0 to the J = 1° channels associated with the 4p2P° ion core of Ca II. Autoionization and channel mixing of the observed J = 1° channels are correlated using methods based on multichannel quantum defect theory.
