State-resolved valence shell photoionization of Be-like ions: experiment and theory

Abstract

High-resolution photoionization experiments were carried out using beams of Be-like C${}^{2+}$, N${}^{3+}$, and O${}^{4+}$ ions with roughly equal populations of the ${}^1$S ground-state and the ${}^3$P${}^o$ manifold of metastable components. The energy scales of the experiments are calibrated with uncertainties of 1 to 10 meV depending on photon energy. Resolving powers beyond 20,000 were reached allowing for the separation of contributions from the individual metastable ${}^3$P${}_0^o$, ${}^3$P${}_1^o$, and ${}^3$P${}_2^o$ states. The measured data compare favourably with semi-relativistic Breit-Pauli R-matrix
