Kummer theory

The theory of Kobozev is open to criticism of the character recently stated by Kummer and Emmett (184), who observed that there was a very rapid exchange between the isotopes of nitrogen in the presence of singly and doubly promoted iron synthetic ammonia catalyst. Kobozev (167) had concluded earlier that iron synthetic ammonia catalysts consisted of an ensemble of iron atoms to which were attached the promoter molecules. Each ensemble was capable of adsorbing only one nitrogen molecule further, in accordance with his theory, these ensembles, separated from one another by geometrical barriers, would make the... 

One model of this would be an infinite spherical potential at r = R so that the boundary condition is simply vJ/(R) = 0. This model has been considered by many authors [9-13] and recently we have found the solution in terms of the Kummer functions [2] and extended the theory to the first-order polarizabilities of such systems [4]. In this case, since we require the solution to be finite at the origin, the energies are found from...

They used the original Temkin-Pyzhev equation with a = 0.5 to correlate the data, but agreement between theory and experiment was even less satisfactory than that obtained by Emmett and Kummer [23].
