- The emission of the Auger electrons during the formation of the Mössbauer nucleus $\text{}^{57}Fe$ leads not only to the formation of multicharged $\text{}^{57}Fe^{n+}$ ion, but also to the appearance of the Auger blob, a cloud of several hundreds of ion-electron pairs ($H_2O^{+}$, e¯) in the solvent around the Fe ion. Fast radiation-chemical reactions therein determine the experimentally observable ratio of the yields of final chemically stable charged states of the Mössbauer ions ($Fe^{3+}$ and $Fe^{2+}$). This ratio strongly depends on reaction rates constants between $H_2O^{+}$, e¯, and the solute S. We have shown that in contrast to radiation chemical data the reactivity of $NO_{3}^{-}$ anions with quasi-free track electrons in frozen aqueous solutions exceeds those of $H_{3}O^{+}$, $ClO_{4}^{-}$, and $HSO_{4}^{-}$ ions only by a factor of three instead of ≈ 100 which follows from the radiation chemical experiments.
