Cross sections for electronic excitation of H_2O by low-energy electrons have been studied using the Schwinger multichannel method. Differential and integral cross sections for excitation of the (3a_1→3sa_1)^3A_1 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 (A^2Σ^+) produced via dissociative electron-impact excitation of H_2O in this energy range is encouraging.
