In the present work, we report theoretical differential and integrated cross sections of the elastic scattering process for sub-thermalization electrons (Einc ffi 10 meV-10 keV) and 1 keV-1 MeV protons in water vapour. The calculations are performed within the quantum mechanical framework for electrons whereas classical calculations are provided for protons. The results obtained in this free-parameter theoretical treatment are compared to available data and quantitative differences are reported
