Description
The ultrafast relaxation of small clusters immediately after ionization
is studied. For small Hg$_n$ clusters we determine the
fragmentation-time distributions induced by ionization. A dramatic
change of the fragmentation behaviour occurs when the temperature before
ionization reaches the melting point of the neutral clusters. The
ultrafast dynamics depends nonlinearly on initial conditions regarding
atomic positions and velocities. The resultant largest Lyapunov exponent
increases strongly upon ionization.
