M. Abstract This paper describes new features in the beryllium and magnesium absorption spectra from 2000 to 500 A. The observations have been made using two 3-electrode vacuum sparks, one serving as a back- ground source, the other as a source of the absorbing metallic vapor. New auto-ionized line series have been identified and associated with transitions from the ground state to two-electron excitation states. Most of these resonances, owing to the interaction of the excited states with the photo-ionization con- tinuum, present a shape which can fit into the general profile formulated by Fano's theory Publication: The Astrophysical Journal Pub Date: August 1969 DOI: 10.1086/150126 Bibcode: 1969ApJ...157..945M full text sources ADS |
