Abstract
Triple differential cross section calculations for the ionization of several valence orbitals of the water molecule by electron and positron impact are reported. We found a very good agreement with the experimental data in case of the almost spherical 2A1 orbital. By changing the projectile’s charge, significant differences were observed between the electron and positron TDCSs.
