Abstract

Absolute total cross sections for electron-impact excitation of the [Formula Presented] and [Formula Presented] transitions in [Formula Presented] were measured using the merged electron-ion beams energy-loss technique. The results are compared to [Formula Presented]-matrix close-coupling theory, which predicts a strong resonance enhancement of the cross section near the threshold for excitation of the [Formula Presented] state and this is confirmed by the experiments. The observed disagreement between theory and experiment for the dipole excitation is suggested to be due to resonance interference.
