【 摘 要 】

Photoionization cross sections for the excited states belonging to configurations of 1s22s2pm(m 5-2) of Neon ions are calculated in the region of double K-vacancy resonances in a close-coupling approximation. Autoionization widths of the double K-vacancy states are obtained from the cross sections by fitting a Fano profile.
