The angular distributions of electrons elastically scattered from H{sub 2}O have been measured by electron impact using a modulated crossed-beam method. The energy and angular range measured were from 30 to 200 eV and 12{degree} to 156{degree}, respectively. The present results show a high backward scattering for low incident energies, but this falls off for high incident energies. The present results are in qualitative agreement with the measurements of Danjo and Nishimura (J. Phys. Soc. Jpn. 54, 1224 (1985)) and in quantitative agreement with the measurements of Katase {ital et} {ital al}. (J. Phys. B 19, 2715 (1986)). Agreement between the present results and the calculation of Jain, Tripathi, and Jain (Phys. Rev. A 37, 2893 (1988)) is good except at 200-eV impact.
