Abstract

With the exception of one ¹S term, the whole number of singlet terms which theory predicts for Mn ii in the 3d⁶, 3d⁵ 4s, and 3d⁵ 4p configurations, have been discovered; they give 41 atomic energy levels: 16 even and 25 odd. It has been possible to classify a total of 167 lines, 113 being combinations among these singlet terms, and 54 intercombination lines with quintet and triplet terms, already known.
