Letter to the editor. Observation and interpretation of the metastable 3p(6)3d Ca+ ion spectrum in the 3p excitation region
A measurement of the 3p absolute photoionization cross section of Ca+ ions is reported. The experiments were performed by means of the merged beam technique and utilizing a target ion beam containing both 3p(6)4s ground state ions and 3p(6)3d metastable ions. By combining measurements performed with different fractions of metastable ions it was possible to obtain separate cross section data for the two species and we present here for the first time the photoionization spectrum of the metastable 3p(6)3d state of the Ca+ ion. Comparison with theoretical predictions allows an interpretation of the strongest features in terms of 3p ? 3d transitions.

Abstract

A measurement of the 3p absolute photoionization cross section of Ca+ ions is reported. The experiments were performed by means of the merged beam technique and utilizing a target ion beam containing both 3p(6)4s ground state ions and 3p(6)3d metastable ions. By combining measurements performed with different fractions of metastable ions it was possible to obtain separate cross section data for the two species and we present here for the first time the photoionization spectrum of the metastable 3p(6)3d state of the Ca+ ion. Comparison with theoretical predictions allows an interpretation of the strongest features in terms of 3p ? 3d transitions.
