Phys., 41, 321-336, (1964); http://dx.doi.org/10.1063/1.1725870 Data: table, diagram Energy/Wavelength range: 60 - 100 nm Resolution: 0.05 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH Comments: Absolute photoionization and absorption cross sections of O2 and N2 have been measured in the 600 to 100 Å region. In N2, the spectrum showed many closely spaced narrow absorption bands down to about 750 Å, broad pre-ionized bands of the Hopfield Rydberg series to about 670 Å, and a smooth ionization continuum at shorter wavelengths. Strong absorption continua were found underlying the band structure below 820 Å, and several weak continua were observed in the longer wavelength region.
