The 2p-4d and 2p-4s transition arrays in fluorine-like copper XXI to arsenic XXV spectra

Abstract

Wavelengths and oscillator strengths for the 2s 2 2p 5 -2s 2 2p 4 4d, 4s electric-dipole transitions in fluorine-like ions from copper to arsenic have been calculated using Cowan and Griffin's HXR method (1970) and Slater-Condon theory (1978). Configuration mixing effects have been considered in detail. The predictions are compared with experimental spectra of copper, zinc, gallium and arsenic, obtained by focusing 30 GW laser pulses on to planar targets. The spectra were recorded with a convex-crystal X-ray spectrograph, and lines measured with accuracies of +or-2 to +or-5 mAA are identified with the stronger 2p-4d and 2p-4s transitions.
