The G-values increased with the increase in concentration of bromide ion, correspond to the earlier scavenging time of OH. Furthermore, the G-values decreased with the atomic mass unit of ions. The yield of OH decreases as the time or as the radical density increases. Our results are consistent with them. However our results of heavier ion are not consistent with theoretical analysis of OH yield. Precise analyses are in progress.
