Abstract:
  The absorption cross sections of the Schumann-Runge bands in the
  window region between the rotational lines have been measured in the
  wavelength region 180-195 nm.  The measurements have been done with
  many different pressures of oxygen, 2.5-760 torr, so that the
  pressure- dependent absorption can be separated from the main cross
  sections. The published cross sections [Yoshino et al., Planet. Space
  Sci. 31, 339 (1983)] in the window region are superseded by the
  present cross sections.  The combined cross sections are available at
  wavenumber intervals of ~0.1 cm-1. The Herzberg continuum cross
  sections are derived after subtracting calculated contributions from
  the Schumann-Runge bands and are significantly smaller than any
  previous measurements.
