The yields of HO/sub 2//sup ./ produced in the radiolysis of water by /sup 58/Ni ions having energies up to 460 MeV have been determined. For these radiations the differential yields for HO/sub 2//sup ./ production increase from 0.26 to 0.43 molecules100 eV over an LET range of 260-520 eVA. From these measurements a limiting yield of 0.57 molecules100 eV is estimated for HO/sub 2//sup ./ production by energy deposited in the track core at very high LETs. These studies demonstrate the feasibility of carrying out significant radiation-chemical studies with beams of particles having LETs in excess of 200 eVA.
