title = "Study of the molybdenum solid-plasma transition by femtosecond X-ray Absorption Near Edge Spectroscopy",
abstract = "Warm dense molybdenum produced by femtosecond laser heating is investigated using femtosecond time-resolved X-ray Absorption Near Edge Spectroscopy (XANES) near the Mo L3−edge (2.52 keV). Laser absorption and X-ray absorption measurements are performed, respectively to constrain hydrodynamic macroscopic simulations, and to obtain atomic-scale information on the dynamics of electron and ion structures. Ab initio calculations are performed to interpret XANES spectra. Preliminary results indicate an extremely rapid loss of the crystalline order (100 fs-scale), accompanied by a modification of the 4d−band electronic structure. This paper highlights the impact of the sample surface quality on the data analysis and interpretation.",
