Abstract

The curium spectrum emitted by electrodeless lamps was observed from 2400 to 11 500 Å and the wavelengths of over 13250 lines were accurately measured. Zeeman effect and spectrum-assignment plates were photographed from 2400 to 9000 Å. From data obtained on the spectrum-assignment plates, over 6800 lines were assigned to Cm I and over 4050 lines were assigned to the Cm II spectrum. The analysis of the Cm I spectrum has produced 335 odd levels and 348 even levels that combine to classify over 5025 Cm lines. Only the energy levels are presented here. The Landé g values of most levels have been obtained from the Zeeman effect data and isotope shifts were determined for many levels. These data were useful in the assignment of levels to electronic configurations of Cm I. The ground configuration of Cm I is [Rn]5ƒ7 6d 7s2 and the lowest level of the [Rn]5ƒ87s2 configuration is only 1214 cm-1 above the ground level.
