Abstract

We present improved energy values for 227 known levels of singly ionized praseodymium (Pr), improved wavelengths for 441 spectral lines of Pr II and classifications for 36 lines. These results are from a high-resolution Fourier transform spectrum covering the spectral range from 3260 to 11 700 Å. The correction to old levels ranges from −0.051 to 0.194 cm−1. These results will be useful in further analysis of Pr II and in astrophysical studies of stellar spectra to determine Pr abundance values
