Total cross sections for electrons and positrons colliding with H2O molecules

Abstract
The total cross sections for 1-400 eV electrons and positrons colliding with H2O molecules have been measured using a TOF method. The results for electron collisions were compared with positron collision data and with previous electron collision work. Data for electron scattering and positron scattering almost coincide with each other in the energy ranges above 200 eV and below 2 eV.
