Absolute photoionization cross-sections for the rare gases have been measured from threshold to 125 eV with an accuracy of ±1 to 3% and are presented in both tabular and graphical form. These data are compared with the optical oscillator strength me

The production and subsequent autoionization of the ${\mathrm{Ar}}^{+}{(}^{1}{D}_{2}{)6d}^{\ensuremath{'}}$ satellite state that is formed either by shake-up or recapture during the Auger decay of a $2p$ vacancy in Ar has been studied by photoelectro

Using synchrotron radiation as a continuum light source, dissociative photoionization of SO2 has been studied in the photon-energy region of 16–120 eV. Ion branching ratios were obtained by analyzing time-of-flight mass spectra and were converted t

Dissociative photoionization of O2 is studied by an energy–mass analyzing system and synchrotron radiation. The kinetic energy distribution spectra of the O+ ion fragments and the dissociative photoionization efficiency curves for the O+ fragments

We report measured partial cross sections for the fragments from dissociative photoionization of N2and O2over the photon energy range of 100 to 800 eV. The partial cross sections were found to follow a power law of the form (hν)−α, wherehν is th

The cross sections for double photoionization of helium and the ratios of double to single ionization have been measured from the double-ionization threshold to 820 eV. The results are in very good agreement with several recent calculations.

Relative photoionization cross sections for and produced by the Auger decay of a 1s hole in atomic oxygen were measured by using synchrotron radiation between 525 and 553 eV. Energies and quantum defects of the members of the two Rydberg series conve

The photoionization cross sections for ${\mathrm{Ar}}^{+}$ through ${\mathrm{Ar}}^{4+}$, produced by the Auger decay of a 2p hole in argon, have been measured between 242 eV and 253 eV by the use of synchrotron radiation. The high resolution of the m
