Abstract
Analysis of recent observations of the Xe III spectrum has yielded revised and extended identifications for the 5s25p3(4S)6s, 7s, 6p, 5d, 6d and 4f levels. Four of the previously known twenty-two levels have been rejected whereas sixteen new levels have been added. The ionization energy has been determined from isoelectronic comparisons. The value arrived at, 250 400 ± 300 cm-1, is some 9000 cm-1 lower than the presently accepted value.
