Systematic multiconfiguration Hartree-Fock results are presented for the transition probabilities and excited-state lifetimes in the term system of the boron atom. Particularly, the interaction between the 1[ital s][sup 2]2[ital s]2[ital p][sup 2] configuration and the 1[ital s][sup 2]2[ital s][sup 2][ital ns] [sup 2][ital S] and 1[ital s][sup 2]2[ital s][sup 2][ital nd] [sup 2][ital D] Rydberg series is considered. Term energies and transition-matrix elements are calculated to convergence using increasing active sets of [ital s], [ital p], [ital d], [ital f], and [ital g] orbitals.
