are their any measurements of elastic/inelastic scattering crossections on liquid water available?
While digging through the literature it seems to me that all validation of geant4-dna was done against data from the gas phase. In general most of the measurements focus on gas phase and extrapolate the results to the liquid phase. With the exception of a publication by Michaud et al measuring low energy electron scattering on ice.
Am I mistaken to say that this approach seems to be reasonable for higher energies, but that it might be problematic in the low energy limit? Don't we have to take into account the special properties (water-water interaction, vibrational excitations, cluster/water-networks, reorientation ...) of liquid water to obtain reasonable crossections?
I would be grateful for any clarification, literature recommendation or information if there was or wasn't done some work in this direction. Thank you very much and best regards. M.Hahn
