Delayed Ultrafast X-ray Auger Probing (DUXAP) of Nucleobase Ultraviolet Photoprotection
B. K. McFarland, J. P. Farrell, S. Miyabe +28
We present a new method for ultrafast spectroscopy of molecular photoexcited dynamics. The technique uses a pair of femtosecond pulses: a photoexcitation pulse initiating excited s…
Multiphoton Ionization as a clock to Reveal Molecular Dynamics with Intense Short X-ray Free Electron Laser Pulses
L. Fang, T. Osipov, B. Murphy +9
We investigate molecular dynamics of multiple ionization in N2 through multiple core-level photoabsorption and subsequent Auger decay processes induced by intense, short X-ray free…
Double core hole production in N2: Beating the Auger clock
L. Fang, M. Hoener, O. Gessner +16
We investigate the creation of double K-shell holes in N2 molecules via sequential absorption of two photons on a timescale shorter than the core-hole lifetime by using intense x-r…
Strong charge transfer effects in the Mg2p^{-1} core-level spectrum of MgB_2
N. V. Dobrodey, A. I. Streltsov, L. S. Cederbaum +2
The two available Mg2p^{-1} spectra of the recently discovered high-temperature superconducting MgB_2 crystal exhibit interesting structures, but contradict each other. This motiva…
