Energy loss and straggling of ions with any velocity in dense plasmas at any temperature

The exact random-phase-approximation dielectric function is used to compute the energy loss and straggling of nonrelativistic charged particles in very dense electron fluids $r_s\le 1$ at any degeneracy and for any velocity ratio $\frac{V}{V_F}$. Relevance to ion-driven inertial fusion is stressed.
