In contrast to the single molecule cage of Ru/acac/3 a cage involving wall molecules of RuCp2 is formed in recoil reaction of radioruthenium atoms. Enhancement of the parent yield in RuCp2 is ascribed to the larger size of the cage /effective hot reaction zone/ compared to the case of Ru/acac/3. A normalized appearance energy technique has been applied to estimate energy /AE adj x / necessary for caging the recoil atom in RuCp2. AE adj x is about twice as large as caging energy CE. The relation of AE adj x to CE in RuCp2 is nearly the same as that of AEx to bonding energy BE in Ru/acac/3.
