Mass Spectrometry Techniques and Applications

Nitrogen gas was condensed on a target at 4°K and bombarded with electrons of medium energy (3 to 50 kv). Emission spectra were obtained in the ultraviolet (2200–4000 A), visible (4000–7000 A), and near infrared (7000–8800 A) spectral regions. The change of these spectra as a function of the intensity of the bombarding electrons was investigated and the influence of impurities of oxygen and argon was studied. Half-life measurements were made of the intense lines and bands. The results obtained by the bombardment technique are compared with those obtained recently by the discharge method.
