摘要：

In the first direct application of the electron-photon coincidence technique for differential cross-section measurements, experimentally determined ratios of the differential cross sections for the electron impact excitation of the 1 S1→2 P1 to the 1 S1→3 P1 transitions are presented at 30 and 40 eV incident electron energies. Differential cross sections for the 1 S1→3 P1 transitions are derived by normalizing these ratios to available experimental differential cross sections for the 1 S1→2 P1 transition. © 1995 The American Physical Society.
