Wavelengths, radiative transition probabilities, Auger energies, and Auger rates have been calculated relativistically for 1s2s/sup 2/2p/sup 2/, 1s2s2p/sup 3/, and 1s2p/sup 4/ configurations of the boron isoelectronic sequence, in terms of the multiconfiguration Dirac-Fock model. Ions with atomic numbers from Z = 6 to 54 are included. The generalized Breit interaction, quantum-electrodynamic corrections, and relaxation are taken into account in the calculations of transition energies. Transition rates are computed in intermediate coupling, including configuration interaction within the same complex. It is found that the effects of relativity play a major role in the forbidden transitions, and also become quite important for allowed transitions for Z greater than or equal to 20. Configuration interaction is found to affect transition rates by as much as a factor of 2 for light ions.
