Abstract

The energy balance of the water molecule ionization by a monoenergetic electron beam with the energy of primary electrons in the interval of 15–1000 eV has been calculated. The dependences of the ionization cost on the water ionization degree within the interval from 0 to 0.1 are obtained. The ionization cost is shown to increase with the ionization degree. In particular, for a primary electron energy of 1000 eV, it increases from 25.26 to 52.45 eV in the examined ionization degree interval.
