Electron tunneling reactions between metal compounds

Electron tunneling reactions between metal compounds 

The fact that the rate of reaction (7) is independent of temperature in the range of 4.2-77 K under the conditions when the samples studied at 4.2 and 77 K were irradiated at the same temperature, 77 K, points to the non-activated tunneling mechanism of reaction (7) and to the absence of reagent diffusion both at 4.2 and 77 K. By analogy, one can assume that the other reactions also occur via electron tunneling. The distances of electron tunneling to acceptors at 77 K within t = 103 s, estimated in the same fashion as in the previous sections, proved to equal 26, 24, and 21A for reactions (6), (7), and (9), respectively. 

The parameters ve and ae for the reactions, considered above, of organic ion radicals, inorganic ion radicals, and metal compounds calculated from the values of / and Rt using the procedure described in Chap. 5, Sect. 2.1.1, are summarized in Table 1. In view of the possible decrease in the radiation yield of ion radicals and Cd(I) and Ni(I) compounds because of the possible
