Photoionization of the scandium atom. II. Classifications

In this paper we use the calculated photoabsorption cross section and scattering parameters to classify most of the autoionizing lines reported by Garton et al. [Proc. R. Soc. London Ser. A 333, 1 (1973)]. This study proves the capabililty of eigenchannel R-matrix calculations to provide spectroscopically useful information on the complicated spectra of transition-metal atoms. We present cross sections for the six optically allowed combinations 4${\mathit{s}}^2$3d ${}_{}{}^2{}_{}{}^{}$ ${\mathit{D}}_{3/2,5/2}$→$1^{\mathit{o}}$/2,$3^{\mathit{o}}$/2,$5^{\mathit{o}}$/2,$7^{\mathit{o}}$/2 from near the (4s3d${)}^3$D thresholds to the (3${\mathit{d}}^2$ ${)}^3$F thresholds.
