Electrodeless-discharge tubes operated in a field of 32 215 G have given Zeeman patterns for 223 P ii spectral lines from 2285 to 7846 Å and yielded 76 Landé g factors. There is good agreement between these g values and those calculated from wave functions obtained by least-squares fitting of energy levels for the single configurations, 3p4p, 3p5p, 3p4f, 3p4s, 3p5s, and 3p6s. However, even when configuration interaction is introduced in the multiconfiguration case, 3s3p3–3p3d–3p4d–3p5d, experimental energy levels will not give good agreement with the corresponding calculated values unless LS-dependent parameters are used in the least-squares fitting. The newly obtained g factors, combined with the predictions of the least-squares energy-level fitting process, have forced a rejection of one even and two odd previously found levels, established nine new levels, reclassified three even and ten odd levels. The new levels belong to the now completed configurations 3p5p and 3p5d. A careful search for transitions to support poorly established levels yielded 44 new lines that confirm newly found levels and fill gaps in the previously known level array.
