Abstract
Femtosecond laser pulses have opened new frontiers for the study of ultrafast phase transitions and
nonequilibrium states of matter. In this Letter, we report on structural dynamics in atomic clusters pumped
with intense near-infrared (NIR) pulses into a nanoplasma state. Employing wide-angle scattering with
intense femtosecond x-ray pulses from a free-electron laser source, we find that highly excited xenon
nanoparticles retain their crystalline bulk structure and density in the inner core long after the driving NIR
pulse. The observed emergence of structural disorder in the nanoplasma is consistent with a propagation
from the surface to the inner core of the clusters.
