Figure:
The top graph shows the principal squared radii of gyration
(left-hand axis,
2) of the
552-atom cluster of LaF3 as it was heated from 10 K to above its
vaporization temperature. The dotted line shows the variation of
temperature (right-hand axis). The inset shows, on the same time
axis, the expansion of the cluster after evaporation: here the
radii of gyration are plotted, again in
2, on the
right-hand axis of the inset. The vibrations in the solid regime
(region A) are enlarged in the central graph: the averages over the
period from 2 to 12 ps have been subtracted off. The bottom graph
shows the oscillations of the liquid drop (region B) after 31-point
moving averaging. The solid, dash-dotted and long-dashed lines
correspond to the maximum, intermediate and minimum squared radii
of gyration respectively.
