Configurations 3d n 4p in Singly Ionized Atoms of the Iron Group.

Abstract
Experimental levels of the configuration 3dn 4p in the second spectra of the iron group were compared with corresponding calculated values. Besides the electrostatic and spin-orbit interactions the α, β and T corrections were considered in the individual and general treatments. The insertion of the parameters β and T improved the results by about 21 percent. The rms error on fitting 703 levels by means of 21 free interaction parameters was 231 cm-1. Altogether 912 energy levels were predicted.
