Fast transient growth of hydrodynamic perturbations due to nonmodal effects is shown be possible in an ablation flow relevant inertial confinement fusion (ICF). Likely arise capsule ablators with material inhomogeneities, such growths appear too fast detected by existing measurement techniques, cannot predicted any the methods previously used for studying instabilities ICF, yet could cause earl...

The computation of dipole matrix elements plays an important role in the study of absorption or emission of radiation by atoms in several fields such as astrophysics or inertial confinement fusion. In this work we obtain closed formulas for the dipole matrix elements of multielectron ions suitable for using in the framework of a Relativistic Screened Hydrogenic Model.
