• The main gaseous products in the radiolysis of solid succinic acid are CO<SUB>2</SUB>, CO, and H<SUB>2</SUB>. It was found that the <I>G</I>(CO+H<SUB>2</SUB>) from the powder is much higher than that from the single crystal, while there is no difference in <I>G</I>(CO<SUB>2</SUB>) between the powder and the single crystal, indicating that CO<SUB>2</SUB> is produced homogeneously in the solid. The clear difference in the <I>G</I>(CO+H<SUB>2</SUB>) between the powder and the single crystal cannot be attributed to the analytical procedure, the secondary reaction of CO, or the presence of H<SUB>2</SUB>O as an impurity. It may be due to the difference in the primary process of the radiolysis. It is conceivable that the mobile active entity formed by the γ-irradiation of the crystal migrates to the special reaction sites and produces CO and H<SUB>2</SUB>. The difference in <I>G</I>(CO+H<SUB>2</SUB>) may also be due to the different numbers of the sites between the powder and the single crystal. It is discussed whether the mobile entity is a cation, an electron, or an exciton.
