Fig. 4 Snapshots from the real-time evolution of the nuclear density of the D
+
2 due to a Gaussian laser pulse of peak intensity
1 × 10 14 W/cm 2 and 10 fs duration. The nuclear density exhibits
interference effects and splits at larger distances around θ = π/2 . The
instantaneous intensity is shown in the individual snapshots. The yellow cross denotes the position of the LICI. All panels show the results
of the full 2d calculation. Note the jump in the interatomic scale
