Adding a 10-fold excess of XeF{sub 2} to Am(III) in 1.5-2.5 M KHCO{sub 3} or 1.5 M KHCO{sub 3} + K{sub 2}CO{sub 3} (pH < 11) quantitatively forms Am(IV) within the time of mixing. The stoichiometry coefficient n = {Delta}[Am(IV)]/{Delta}[XeF{sub 2}] under optimal conditions (1.5 M KHCO{sub 3}) is less than 0.23. In 3.4-5.9 M K{sub 2}CO{sub 3}, Am(III) was not oxidized. The mechanism of Am(III) oxidation is discussed. Experiments with Tb(III) showed that it is not oxidized under all studied conditions.
