Relative photoionization cross section of atomic selenium between 800 and 1400 Å

Abstract
The relative photoionization cross section of atomic selenium has been measured in the 800–1400-Å region. The absorption cell consisted of a flash pyrolysis system, and the background continuum was provided by a BRV source or a Garton flash. A majority of the absorption features appearing below 1272 Å has been identified.
