Some energy levels and lifetimes in B II have been studied using classical emission spectroscopy and beam-foil spectroscopy. Revisions are suggested for the excitation energies of the 2s3s 1S and 2s5p 1P 0 levels. The 2p3s 1P 0 and 2s6p 1P 0 terms have also been located. Lifetimes have measured for the 2s2p 1P 0, 2p 21S, 2s3d 1D and 2p 23P levels. The results are compared with theoretical data.
