We have evaluated the spatial distribution of energy deposition by proton beams in liquid water using the simulation code SEICS (Simulation of Energetic Ions and Clusters through Solids), which combines molecular dynamics and Monte Carlo techniques and includes the main interaction phenomena between the projectile and the target constituents: (i) the electronic stopping force due to energy loss...
Energy deposition of MeV electrons in dense plasmas, critical for fast ignition in inertial confinement fusion (ICF), is modeled analytically. It is shown that classical stopping and scattering dominate electron transport and energy deposition when the electrons reach the dense plasmas in the cores of compressed targets, while “anomalous” stopping associated with self-generated fields and micro...
We have measured the stopping powers and straggling of fast, highly ionized atoms passing through thin bilayer targets made up of metals and insulators. We were surprised to find that the energy losses as well as the straggling depend on the ordering of the target and have small but significantly different values on bilayer reversal. We ascribe this newly found difference in energy loss to the ...
Straggling is the broadening of energy distribution a beam charge particle penetrating through material medium. The calculationsrepresenta problem considerable complexity.The theoretical literature on straggling rather limitedcomparedto one stopping cross section. In present work, energyloss has been studied theoretically for interaction ions in target .

The aim of this work is to investigate how the mean energy loss and straggling due to H2 + molecules interacting with silicon are affected by the Coulomb explosion and vicinage effects. To that end, a SIMOX-type sample made up of O and with an appropriate O marker grown over the surface of crystalline Si was employed, allowing to carry out the measurements through the O p , N resonant reaction ...
