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${\mathit{s}}^2$2s2${\mathit{p}}^2$ configuration and the 1${\mathit{s}}^2$2${\mathit{s}}^2$ns ${}_{}{}^2{}_{}{}^{}$S and 1${\mathit{s}}^2$2${\mathit{s}}^2$nd ${}_{}{}^2{}_{}{}^{}$D Rydberg series is considered. Term energies and transition-matrix elements are calculated to convergence using increasing active sets of s, p, d, f, and g orbitals.
