Abstract
The positions of 38 observed levels of the 4f3 configuration of Pr iii were calculated with a rms error of ±168 cm−1, by use of seven adjustable parameters. The interaction with the 4f5d2 levels is discussed. A calculation of the levels of the 4f25d configuration was obtained with a rms error of ±182 cm−1 relative to the 101 observed levels, utilizing 13 adjustable parameters.Keywords
