Identification of high energy lines in the K-LL auger spectrum of N-2

The K-LL spectrum in nitrogen has been measured with a high-resolution electron spectrometer using 1) 3 keV electrons and 2) AIK(alpha) X-rays to produce the initial K vacancy. In the high-energy portion of the Auger spectrum, lines at 383.8 eV and 386.7 eV and a band roughly between 368 eV and 380 eV were found as a result of electron bombardment but were missing with the X-ray irradiation. The reason for these differences is ascribed to the phenomenon of exciting a K electron into an unoccupied molecular orbital followed by autoionization.
