Paper Abstract
X-ray-pump/x-ray-probe spectroscopy allows investigation of ultrafast x-ray induced molecular dynamics. X-ray
absorption and Auger decay leave molecules in manifolds of transient intermediate states in the femtosecond time scale.
By using an x-ray probe pulse, we can image nuclear wavepackets as a function of time using ion-ion coincidence
spectroscopy to record ion momentum distributions and kinetic energy releases (KERs). Numerical simulations, a timedependent
approach that includes both K-shell photoionization and Auger decay, show how the transient intermediate
states are projected onto the KERs. At short time delays, the measurements are sensitive to interatomic interactions,
whereas at longer delays the contribution from separated ions due to dissociative intermediate states becomes
observable. We present simulations for the nitrogen molecule. These simulations have the potential to be extended to
more complex molecules.
