Term Analysis of Fe V

Abstract
The spectrum of Fe V has been observed by using a vacuum sliding-spark discharge and the 10.7-m grazing-incidence spectrograph as well as the 10.7-m normal-incidence spectrograph at the National Bureau of Standards, Washington. Almost 1 000 lines have been identified in the region 302-1 715 Å, and all levels of 3d4and all but one level in each of the configurations 3d34sand 3d34phave been established. The estimated uncertainty of the level values is ±0.4 cm-1. From the complete set of 3d4levels the forbidden lines of Fe V from 828 to 10 000 Å are predicted, and a comparison is made with the spectrum of the star RR Telescopii.
