摘要：

Electron-impact-ionization cross sections to form the parent ions of N2, CO, CO2, CS, S2, and CS2 have been measured with the same apparatus used recently to measure ionization cross sections of 27 atoms with an absolute accuracy of ±10%. The ionization cross sections for CS, S2, and CS2 are measured here for the first time to our knowledge. The results for N2, CO, and CO2 generally agree with previous measurements. A remeasurement of the ionization cross sections of metastable N2 improves upon our previous measurement. © 1990 The American Physical Society.
