The spectrum of singly ionized potassium, KII

Abstract
Using 10.7 m and 3 m normal-incidence vacuum ultraviolet spectrographs, we investigated the spectrum of singly ionized potassium in the regions 495 - 612 angstrom and 1247 - 2150 angstrom. More than 120 new K II lines were identified. The previous study on this spectrum was revised and extended. All levels of the 3p(5)4f and 5f configurations as well as the levels of 3p(5)6f based on the 3p(5) P-2(3/2) core state have now been located. Several new levels of 3p(5)3d were also located. The ionization limit was determined from the 3p(5)nf 1.5[4.5](5) ( n = 4 - 6) series as 255072.8 +/- 1.5 cm(-1)(31.6250 +/- 0.0002 eV).
