Molecular dynamics simulations under CVI initial conditions of Coulomb explosion of (H⁺I²⁵⁺)₂₁₇₁ heteroclusters, portraying the time-dependent narrow distributions P(r) of the H⁺ ions. The Insets show the 2D projections of the initial structure at t = 0 and of the narrow shell of light ions at t = 14 fs, with the x and z axes being given in Å. Open circules mark I²⁵⁺ ions, and black dots mark H⁺ ions.
