  The stopping power of Warm Dense Matter (WDM) is estimated by means of the
individual contributions of free electrons and bound electrons existing in this
special kind of matter, located between classical and degenerate plasmas. For
free electrons, the dielectric formalism, well described in our studies, is
used to estimate the free electron stopping power. For bound electrons, the
mean excitation energy of ions is used. Excitation energies are obtained
through atomic calculations of the whole atom or, shell by shell in order to
estimate their stopping power. Influence of temperature and density is analyzed
in case of an impinging projectile. This influence becomes important for low
projectile velocities and is negligible for high ones. Using free and bound
electron analysis, the stopping power of an extended WDM is inferred from a
dynamical calculation of energy transferred from the projectile to the plasma,
where the Bragg peak and stopping range are calculated. Finally, this
theoretical framework is used to study a typical plasma density profile of a
WDM heated by lasers.
