The chemical effects associated with the β<SUP>−</SUP>-decay of <SUP>144</SUP>Ce(III)-aminopolycarboxylate complexes have been further investigated. The chemical behavior of <SUP>144</SUP>Pr was analyzed kinetically on the basis of the isotopic exchange-reaction mechanism. The formation of the intermediate complex produced by an intramolecular electron transfer of the <SUP>144</SUP>Pr(IV)-aminopolycarboxylate following the β<SUP>−</SUP>-decay of <SUP>144</SUP>Ce(III) complex was also confirmed. In the ethylenediaminetetraacetate and <I>trans</I>-1,2-diaminocyclohexane-<I>N</I>,<I>N</I>′-tetraacetate systems, the values for the bond-rupture of the daughter complex ions are fairly much larger than in the diethylenetriaminepentaacetate system, suggesting that a kinetically-excited intermediate complex decomposes to a free ion to some extent.
