Kadri, J. Schleiffer, J. Adloff] The chemical state of239Np formed in the β-decay of239U produced by thermal neutron capture in239U, has been determined in simple uranium compounds as well as in macrocyclic complexes of this element. It is shown that the behavior of neptunium depends on such factors as the nature of the target, the counter-ion of the complex, the dissolution medium and the pH. The change of the oxidation state of239Np with time and the effect of the presence of macroscopic amounts of238UO 2 2+ and of238U(IV) in the solution have also been investigated. The results are discussed in terms of the hot atom behavior of239U and of the genuine effects of β-decay. Akadémiai Kiadó, 1992 Kadri M.
