Effect of the Tow Approximations of Lindhard on Energy Loss Fluctuation (Straggling) of Diclusters Hydrogen Ions at Low Velocities with No Damping

Saher Mazher | Sana Thamer

Abstract: In this search, we study straggling of dicluster with no damping at low velocities. We use (Na, k, Cs) as targets mediums based on an electron gas model. This work discusses effect of wigner-sitz radius (density parameter rs) and internuclear distance (r12) on stopping power. The results show the linear behavior of the energy loss with the ion velocity obtained under the free electron gas (FEG) and linear dielectric formalism. This search gives detail studying about straggling at different adverbs and effect of different parameters. A program in matlab has been written for execute.
