Abstract

A recent investigation of the spectrum emitted by condensed spark discharges between metallic zirconium electrodes has revealed about 75 new lines of Zr ii in the region between 10 000A and 4800A. Most of these lines are accounted for as combinations between previously known terms. The remaining lines have led to the discovery of a new term, here designated as 4d^{3 2}D. This new term lies highest among those from the low, even electron configurations 4d² 5s, 4d³, and 4d 5s² and conforms to theoretical requirements for a ²D term of its energy and character. It replaces the “doubtful and relatively inconspicuous” term d ²D of the older analysis, which is now rejected as spurious.
