  We have explored the light induced dynamics in superfluid helium nanodroplets
with wide-angle scattering in a pump-probe measurement scheme. The droplets are
doped with xenon atoms to facilitate the ignition of a nanoplasma through
irradiation with near-infrared laser pulses. After a variable time delay of up
to 800 ps, we image the subsequent dynamics using intense extreme ultraviolet
pulses from the FERMI free-electron laser. The recorded scattering images
exhibit complex intensity fluctuations that are categorized based on their
characteristic features. Systematic simulations of wide-angle diffraction
patterns are performed, which can qualitatively explain the observed features
by employing model shapes with both randomly distributed as well as structured,
symmetric distortions. This points to a connection between the dynamics and the
positions of the dopants in the droplets. In particular, the structured
fluctuations might be governed by an underlying array of quantized vortices in
the superfluid droplet as has been observed in previous small-angle diffraction
experiments. Our results provide a basis for further investigations of
dopant-droplet interactions and associated heating mechanisms.
