Observation of subordinate 2p$sup 5$4d--2p$sup 5$3p transitions in neon- like ions from Ca XI to Ni XIX

We report the first identification of subordinate 2p$sup 5$4d-2p$sup 5$3p transitions in the neon-like ions Ca xi through Ni xix. Such transitions between excited levels have not previously been reported for ionization stages higher than Al iv, though the resonance lines are known through Zn xxi in the neon isoelectronic sequence. Measurement of the solar flux in such transitions may aid in establishing the relative importance of the several cascade processes giving rise to the observed Fe xvii resonance lines.
