Abstract

Beam-foil spectra of nitrogen were obtained for particle energies between 0.25 and 2.0 MeV in a wavelength range between 1050 and 3000 Å and up to 5.5 MeV between 2000 and 5000 Å. Most of the spectral lines are ascribed to known transitions in N i–vi. Many Si i–vi transitions could also be identified in the spectrum of the mass-28 beam. Twenty-five decay times of nitrogen were measured. In some cases, the experimental mean lives differ by factors as large as 4 from theoretical values.
