The radiation-chemical yields of H3O+ and OH- as determined by nanosecond conductimetric measurements

Abstract

The radiation-chemical yields of ionic species formed upon irradiation of water by 3.5 MeV electrons have been determined directly using dc conductivity and optical measurements. Yields (expressed in μmol J^-1) at 10 and 110 ns after the end of a 10 ns pulse are: for H₃O⁺ = 0.371, 0.320; for OH^- = 0.082, 0.045, and for e^-_aq = 0.299 and 0.275, respectively.
