Abstract : X-ray free-electron lasers (XFELs) made available a new regime of x-ray intensities, revolutionizing the
ultrafast structure determination and laying the foundations of the novel field of nonlinear x-ray optics.
Although earlier studies revealed nanoplasma formation when an XFEL pulse interacts with any
nanometer-scale matter, the formation process itself has never been decrypted and its timescale was
unknown. Here we show that time-resolved ion yield measurements combined with a near-infrared laser
probe reveal a surprisingly ultrafast population (∼12 fs), followed by a slower depopulation (∼250 fs) of
highly excited states of atomic fragments generated in the process of XFEL-induced nanoplasma
formation. Inelastic scattering of Auger electrons and interatomic Coulombic decay are suggested as
the mechanisms populating and depopulating, respectively, these excited states. The observed response
occurs within the typical x-ray pulse durations and affects x-ray scattering, thus providing key information
on the foundations of x-ray imaging with XFELs.
