Abstract
A numerical study of the interaction of short (15 fs), intense (1016 − 2 × 1017 W/cm2), soft X-ray pulses with vanadium targets has been performed by means of a 1D hydrodynamics code. The code which considers the non-equilibrium between electrons and ions, includes a proper treatment of the atomic processes involved in the absorption of x-ray photons and in the evolution of the subsequent heated material. By associating the ablation depth to the spatial profile of the shock wave into the material, numerical values of this ablation depth have been obtained.
