Abstract

The curium emission spectrum from electrodeless lamps has been observed from 2400 to 26 500 Å. About 30% of the 14,250 observed lines have been assigned by experimental methods as Cm ii lines. Analysis of the spectrum has produced 432 odd levels and 162 even levels of Cm ii that combine to classify more than 4,100 curium lines. The energy levels are listed, and most have Landé g values from Zeeman effect data as well as isotope shift values. Many levels have been assigned to electronic configurations and terms by use of isotope shift and Lande g values. A table containing the lowest level found for each of the eight identified electronic configurations is given. The ground state of the ion is the 8S7/2° level of the (Rn) 5f77s2 configuration. The next electronic configuration is 5f87s, whose lowest level is the 8F13/2 level at 2093.87 cm−1.
