Abstrakt:	The mechanism leading to the formation of nitrous oxide involves NO, HT $\mathrm{N}{\mathrm{O}}_2$ ht and H SP I • i sp . Similar experiments with plutonium(IV) and plutonium(VI) are also made and compared to the experiments without sulfamic acid. HT $\mathrm{H}\mathrm{N}{\mathrm{O}}_2+{\mathrm{H}}_2\mathrm{N}\mathrm{S}{\mathrm{O}}_3\mathrm{H}->{\mathrm{N}}_2+{\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4+{\mathrm{H}}_2\mathrm{O}$ ht Graph (2) HT $k_2=33.5\mathrm{L}-\mathrm{m}\mathrm{o}{\mathrm{l}}^{-}-{\mathrm{s}}^{-}$ ht Graph Experiments were prepared following the procedures provided hereinafter and the compositions of plutonium solutions obtained this way are detailed in Table 2.
