Abstract
The precise details of the interaction of intense X-ray pulses with matter are a topic of intense interest to researchers attempting to interpret the results of femtosecond X-ray free electron laser (XFEL) experiments. An increasing number of experimental observations have shown that although nuclear motion can be negligible, given a short enough incident pulse duration, electronic motion cannot be ignored. The current and widely accepted models assume that although electrons undergo dynamics driven by interaction with the pulse, their motion could largely be considered ’random’. This would then allow the supposedly incoherent contribution from the electronic motion to be treated as a contin..

The authors acknowledge the support of the Australian Research Council Centre of Excellence in Advanced Molecular Imaging. Portions of this research were carried out at the LCLS, a national user facility operated by the Stanford University on behalf of the U.S. Department of Energy, Office of Basic Energy Sciences. We acknowledge the travel funding provided by the International Synchrotron Access Program managed by the AS and by the Australian government. In addition, some of this research was undertaken on the MX1 and MX2 beamlines at the AS, Victoria, Australia. Author contributions: B.A. was responsible for planning and managing all experimental aspects of the project. Experiments were designed by B.A., R.A.D., VS., CD., and G.J.W. B.A., H.M.Q., K.A.N., and R.A.D. wrote the original LCLS proposal. D.W., R.A.D., R.A.R., A.V.M., E.C., and S.W. carried out the simulation work. B.A., R.A.D., CD., VS., M.W.M.J., R.A.R., N.G., F.H., G.J.W., S.B., M.M., M.M.S., A.G.P, C.T.P, A.V.M., and K.A.N, collected the experimental data at the LCLS. S.W., V.A.S. and R.A.D collected experimental data at the Australian Synchrotron. C.T.P. and A.V.M. led the experimental data conversion and analysis. B.A., CD., N.G., and E.B. were responsible for the sample holder design and testing. R.A.R, B.A., S.W., A.V.M and H.M.Q wrote this manuscript. The formulation of electronic damage within coherence theory is performed by H.M.Q. and K.A.N.; R.A.D. conceived the idea to apply this formalism to C60.
