Abstract :

The effects of multiple ionization of water molecules on the yields of formation of free radical and molecular species, including molecular oxygen, in the radiolysis of pure, deaerated liquid water is investigated by Monte Carlo. The results revealed a steep increase in the initial and primary yields of molecular oxygen with increasing linear energy transfer (LET), giving support to the 'oxygen in heavy-ion tracks' hypothesis.
