Fig. 2.

The radial distribution functions P(r) for the (D₂)₂₁₇₁, (HT)₂₁₇₁, and (DI)₂₁₇₁ clusters in a Gaussian laser field (I_M = 10¹⁸ W·cm⁻² and τ = 25 fs) at various times t − t_s. t_s is the starting time of the simulation with respect to the maximum of the Gaussian laser field envelope located at t = 0 (see Supporting Text). For the heteronuclear (HT)₂₁₇₁ and (DI)₂₁₇₁ clusters, P(r) = P(r)Δr is drawn separately for each ion (as marked on the images), exhibiting shell formations of the nonoverlapping distributions of different isotope/element ions at times t − t_s > 0. These shells expand with different velocities. (Insets) The time-dependent increase of the first moments 〈R〉 of P(r) relative to the first moment 〈R〉₀ at t − t_s = 0. Data are presented for different ions, as marked on Insets.
