Fig. 3: Evolution of the He density distribution.
From: Ultrafast relaxation of photoexcited superfluid He nanodroplets

In this simulation, the probability distribution of He\({}^{* }\) is represented as a yellow dot. The initial position of He\({}^{* }\) is 0 (left column) and at 0.7 nm (right column) away from the droplet surface.
