【 摘 要 】

Synopsis The B-spline Breit-Pauli R-matrix method has been used to calculate electron excitation collision strengths for a wide range of transitions between the first 220 fine-structure levels of O III. The calculation includes levels of the 2s22p2, 2s2p3, 2s22p3l, 2s22p4l and 2s2p23l configurations. The present work considerably improves the existing calculations for oscillator strengths and collision strengths of O III.
