Abstract:
:The W values of protons in water vapour were measured for energies from 1 keV to 100 keV with uncertainties lower than 1%. To study the energy and phase dependence of W values, the W values of protons in water vapour and liquid water were calculated for energies from 0.1 keV and 10 MeV and then compared to the experimental results of this work.
