Abstract

The beam-foil technique is applied to 17 transitions due to nitrogen ions in the wavelength region 1900–4900 Å Radiative lifetimes are given for the following levels: (3p ¹S, 3p ¹D, 4s ³P⁰, 4f ^1,3F, 4f ³G) for N ii;(3p ⁴P, 3p ²D, 3d ⁴P⁰, 3d ⁴D⁰, 3d ⁴F⁰, 4p ²P⁰, 4f ⁴D, 4f ²F, 4f ²G, 6g ²G) for N iii; (3p ³P⁰) for N iv. These results are compared with previously published data and with values calculated from theoretical wavefunctions.
