The nitrogenKagr; emission spectrum excited by electron bombardment of nitrogen gas was obtained on a single planar crystal spectrometer with photon counting. The experimental profile is in fair agreement with a calculated profile based on molecular orbital theory and the single vacancy states measured by xhyphen;ray photoelectron spectroscopy. Evidence is presented to suggest that some of the emission intensity on the highhyphen;energy side of the main peak is due to ``resonance radiation.'' To fix the energy scale of the spectrum, the effective 2dspacing of the analyzing lead myristate crystal was experimentally determined.
