| Abstract: | Our previous theoretical work one
− − H2O scattering has been modified and extended to intermediate and high energiesE
i. Using the Bethe plot, we compare the present inelastic cross-sections with the experimental ionization cross sections. Total
cross-sections are analytically represented asQ
TOT(cm2)=a.(E
