The curium spectrum emitted by electrodeless lamps was observed from 2400 to 11
500 Å and the wavelengths of over 13 250 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]5f7
6d 7s2 and the lowest level of
the
[Rn]5f87s2
configuration is only 1214 cm−1 above the ground level.

Odd levels of Cm i. Level energy and isotope shifts are in
cm−1, observed g values are in
Lorentz units, and a P after an observed g value indicates
a perturbed Zeeman splitting.

TABLE III
Even levels of Cm i. Level energy and isotope shifts are in
cm−1, observed g values are in
Lorentz units, and a P after an observed g value indicates
a perturbed Zeeman splitting.
Based on 8S∘ only.
Lowest level found. The predicted lowest level, , has not been found.
TABLE V
Comparison of observed and calculated energy and g values
for levels of the
5f76d7s2
configuration. Level compositions are given and the parameters used are
listed at the end of the table.

TABLE III
Even levels of Cm i. Level energy and isotope shifts are in
cm−1, observed g values are in
Lorentz units, and a P after an observed g value indicates
a perturbed Zeeman splitting.
Based on 8S∘ only.
Lowest level found. The predicted lowest level, , has not been found.
TABLE V
Comparison of observed and calculated energy and g values
for levels of the
5f76d7s2
configuration. Level compositions are given and the parameters used are
listed at the end of the table.
