Abstract
The yield of ferric ions in the radiolysis of an aqueous ferrous ammonium sulfate solution has been determined in the very high LET (linear energy transfer) range. The radiations used were ions of carbon-12 and nitrogen-14, which were accelerated by means of the IPCR cyclotron and which had energies (Es) of 31–77 MeV for C-ions and of 17–78 MeV for N-ions; the LET ranges for water were 24–46 eV/A and 26–85 eV/A respectively. From the plot of G(Fe3+)Es vs. Es, the value for G(Fe3+) at an infinite LET was found to be in the vicinity of 2.9. It has also been shown that there is a substantial difference in the instantaneous yield (Gi) between the two ion radiations of the same LET; this may be ascribed to the differences in the track structures of the heavy-ion radiations.
