摘要：
Cross sections for electronic excitation of H2O by low-energy electrons have been studied using the Schwinger multichannel method. Differential and integral cross sections for excitation of the (3a13sa1)3A1 dissociative state are reported for impact energies of 12, 15, and 20 eV. A comparison of the calculated integral cross sections with emission measurements for OH (A2+) produced via dissociative electron-impact excitation of H2O in this energy range is encouraging. © 1990 The American Physical Society.
