Figure 8.

Comparison of the internal energy deposition from electron capture by $\mathrm{Mg}{\left({\mathrm{H}}_2\mathrm{O}\right)}_n^{2+}$, n = 4 – 6, 32, with adiabatic ionization energies of $\mathrm{Mg}{\left({\mathrm{H}}_2\mathrm{O}\right)}_n^{+}$ from BLYP (□) and MP2 (◊) calculations from [69] as a function of cluster size. The average energy deposition (E_avg; ▲), as well as the range of energies from the maximum observed (E_MO) to the maximum possible (E_UL), are indicated. For $\mathrm{Mg}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4^{2+}$, no upper limit (E_UL) is indicated because MgOH⁺ is formed. (see text).
