Total and dissociative photoionization cross sections of N2from threshold to 107 eV

摘要

The absolute cross sections for the production of N+and N+2have been measured from the dissociative ionization threshold to 115 Aring;. In addition, the absolute photoabsorption and photoionization cross sections are tabulated between 114 and 796 Aring;. The ionization efficiencies are also given at several discrete wavelengths between 660 and 790 Aring;. The production of N+fragment ions are discussed in terms of the doubly excited N+2states with binding energies in the range 24 to 44 eV.
