Mean lives of eight terms in B IV and three in B V have been measured using the techniques of beam-foil spectroscopy. The terms in B IV and the measured mean lives are (in picoseconds): ls2p1p0, <5; ls4d1D, 117 ± 16; ls3d1D, 63 ± 3; ls3s1S, 393 ± 4; ls4d3D, 131 ± 8; ls3p3P0, 222 ± 4; 1s3d3D, 59 ± 3; ls3s3S, 474 ± 28. These results and those for B V are compared with theory and previous experimental results.
