摘要
Allowed Δn=0 transitions of highly ionized metal atoms,which may appear in the solar spectra as well as in spectra from the high-temperature tokamak plasmas,lie in the extreme vacuum UV(XUV) region,100A≤λ≤200A.Here we report our theoretical calculation of the Δn=0 transitions of C-like cobalt ions;it is in good agreement with the experimental measurement.Such theoretical calculations of the transition wave lengths and their oscillator strengths should be very helpful to identify the XUV spectra.
