Production of H2O radical in the Track of High-Energy Carbon Ions

Article abstract of DOI:10.1021/j100266a005

The radiation chemical yields of H2O radical produced by irradiating water with 12C ions of 37-100-MeV initial energy have been determined. these data have been combined with previous values for lower energy carbon and helium ions to obtain the differential yields over the range 2-102 eV/Angstroem.The close similarly between the yields for helium and carbon ions of the same LET suggests that the reaction volume of interest extrends somewhat beyond the track core, especially for helium.LET appears to be a useful parameter to describe the production of H2O radicals in the tracks of heavy particles.
