Differential cross sections for excitation of the 3{ital s} {sup 3}{ital S}{sup 0} and 3{ital p} {sup 3}{ital P} states of atomic oxygen by electron impact are calculated in a close-coupling approximation at energies 13.87, 20, 30, and 50 eV. We include 2{ital p}{sup 4} {sup 3}{ital P}, 3{ital s} {sup 5,3}{ital S}{sup 0}, 3{ital p} {sup 5,3}{ital P}, 4{ital s} {sup 5,3}{ital S}{sup 0}, 3 {sup 5,3}{ital D}{sup 0}, 4{ital p} {sup 5,3}{ital P}, and 3{ital s}{prime} {sup 3}{ital D}{sup 0} states of atomic oxygen in the close-coupling expansion. The present results are in good agreement with the recent experiments for the resonance {sup 3}{ital P}--3{ital s} {sup 3}{ital S}{sup 0} transition, but there are discrepancies between theory and experiment for the electric dipole-forbidden {sup 3}{ital P}--3{ital p} {sup 3}{ital P} transition.
