Absorption spectrum of Sr i between 1400 and 1900 Å

Abstract
The high-dispersion absorption spectrum of Sr i is reported for the 1400–1900-Å region. Observations include transitions from 5s2 1S0 to the J = 1° channels of Sr i associated with the excited 4d 2D and 5p 2P∘ ion cores of Sr ii. Autoionization and channel mixing of the observed J = 1° channels are correlated by using methods based on multichannel quantum-defect theory.
