Beam-foil spectroscopy of oxygen in the wavelength region from 270 to 490 Å
Abstract
The beam-foil technique was used to study the spectrum of oxygen between 270 and 490 A, and the measured mean lives of 18 terms of O II, O III, and O IV are reported. All observed cascade components have been assigned. Decay curves for 16 features were obtained, and the procedures for measuring the decay curves are explained. The exceptions to the agreement of theoretical and experimental values are considered. The mean-life results were used to calculate f-values, and some discrepancies with experimental results are discussed.
