Differential, integral, and momentum-transfer cross sections for the rotationally elastic and inelastic scattering of electron by the BH{sub 2} radical at low collision energies (0-8 eV) are reported in a 22-state molecular R-matrix method. The excitation cross sections from the ground X {sup 2}A{sub 1} state to the first two excited states {sup 2}B{sub 1} and {sup 4}A{sub 2} are calculated as well, for incident electron energies from the respective thresholds up to 8 eV. Configuration-interaction wave functions are used to represent the target states which account for the correlation effects. Four shape and three Feshbach resonances are detected. The Born-closure approximation is applied for the elastic and dipole-allowed transitions to account for the l>4 partial waves excluded from the R-matrix calculations.
