Abstract
The core-excited quartet and doublet spectra of B III, produced by foil excitation of fast B+-ion beams, have been studied in the wavelength region 300-6300 Å. A large number of new transitions have been observed, for the first time allowing a detailed test ot theoretically predicted core-excited B III 4L- and 2L-term schemes. For a number of quartet states, the line assignments are supported by lifetime measurements. All the assigned, core-excited spectral lines are in excellent agreement with theoretical predictions by Chung et al. These predictions have been extended to include quartet states with L > 2.Keywords
