OHRW95 R. Otto, H. Hühnermann, J. Reader, and J.-F. Wyart, J. Phys. B 28, 3615 (1995). Tables 1 and 4 of this reference comprise the most extensive published data on energy-level classifications for Pm II lines. The wavelengths in Table 1 were apparently derived from the levels by using an inaccurate formula for the dispersion of air; the resulting values are longer than the more accurate values in [RCWM80] by 0.02 to 0.05 Å.
RCWM80 J. Reader, C. H. Corliss, W. L. Wiese, and G. A. Martin, Natl. Stand. Ref. Data Ser., Natl. Bur. Stand. (U.S.) 68 (1980). The Pm II wavelengths in this reference were taken from [MSB51] and [DR72a]. The energy-level classifications for the Pm II persistent lines given here are from [DR72a] and [OHRW95].
