Relativistic distorted-wave collision strengths have been calculated for the 49 optically allowed transitions with in the 67 B-like ions with nuclear charge number in the range . The calculations were made for the four final, or scattered, electron energies , 0.42, 0.80, and 1.40, where is in units of Ry with . In the present calculations, an improved 鈥渢op-up鈥?method, which employs relativistic plane waves, was used to obtain the high partial-wave contribution for each transition, in contrast to the partial-relativistic Coulomb-Bethe approximation used in previous work by Zhang and Sampson [H.L. Zhang and D.H. Sampson, At. Data Nucl. Data Tables 56 (1994) 41]. In that earlier work, collision strengths were also provided for B-like ions, but for a more comprehensive data set consisting of all 105 transitions, six scattered energies and the 85 ions with in the range . The collision strengths covered in the present work should be more accurate than the corresponding data given by Zhang and Sampson [H.L. Zhang and D.H. Sampson, At. Data Nucl. Data Tables 56 (1994) 41] and are presented here to replace those earlier results.
