Abstract
We report measured and calculated differential cross-sections for inelastic scattering of low-energy electrons by water leading to excitation of the dissociative (1b_1 → 4ɑ_1) ^(1,3)B_1 states. The measurements were taken using conventional energy-loss spectroscopy at incident energies of 9, 10, 12, 15, and 20 eV for scattering angles from 10◦ to 130◦. The calculations were carried out using the Schwinger multichannel method, with a Born-dipole correction applied in the singlet excitation channel. Integral excitation cross sections for the ᾶ^3B_1 and Ã^1B_1 states are also derived from the differential cross section results.
