Spectral classification using pattern-recognition techniques. II. Application to curium energy levels

Curium energy levels have been classified according to configuration using pattern-recognition techniques. Four features—energy level, Landé $g$, $J$, and isotope shift—have been used to describe each level. Forty levels have been assigned with high probability based on consistent results obtained by various pattern recognition techniques. This represents an increase of 9% for even levels and 19% for odd levels. In addition, 14 levels have been assigned to one of two possible configurations. Pattern recognition in general, as applied to atomic energy-level classification, is discussed.
