Further investigations on doubly excited four-electron ions: beam-foil experiment and MCDF theory
Abstract
In continuation of our previous work on the quintet transitions 1s2s2p^2 ^5 P-1s2s2p3d
^5 P^0, ^5 D^0, results on other n = 2 - n' = 3 quintet transitions for elements N, 0 and F are presented. Assignments have been established by comparison with Multi-Configuration Dirac-Fock calculations. High spectral resolution on beam-foil spectroscopy was essential for the identification of most of the lines. For some of the quintet lines decay curves were
measured, and the lifetimes extracted were found to be in reasonable agreement
with MCDF calculations.
