Area of Science:

  • Atomic and Molecular Physics
  • Ultrafast Spectroscopy
  • X-ray Science

Background:

  • Direct observation of molecular dynamics from x-ray interactions is limited by the availability of bright, short-wavelength femtosecond sources.
  • Understanding ultrafast electronic and nuclear dynamics in molecules under ionizing radiation is crucial.

Purpose of the Study:

  • To directly observe molecular dynamics initiated by soft x-rays.
  • To investigate the role of electron-shakeup processes in molecular fragmentation.
  • To probe ultrafast dynamics inaccessible by other techniques.

Main Methods:

  • Utilized soft x-ray beams from high-harmonic upconversion of femtosecond lasers to photoionize nitrogen molecules.
  • Employed a strong infrared pulse to probe electronic and nuclear dynamics during molecular explosion.
  • Achieved angstrom resolution in real-time observations.

Main Results:

  • Observed substantial molecular fragmentation driven by an electron-shakeup process during soft x-ray photoionization.
  • Documented the rapid change in molecular potential experienced by electrons during fragmentation.
  • Captured real-time, angstrom-resolution dynamics of ionizing radiation effects.

Conclusions:

  • Electron-shakeup is a significant pathway for molecular fragmentation initiated by soft x-rays.
  • The developed technique provides unprecedented real-time insights into molecular dynamics under irradiation.
  • This method opens new avenues for studying the impact of ionizing radiation on diverse molecular systems.
