Using the linear-response dielectric theory, we have investigated the electronic stopping power for slow atoms in solids. The effect of the electrons bound to the projectile is considered according to the Brandt-Kitagawa (BK) model [Phys. Rev. B 25, 5631 (1982)]. Using a local-field-correction dielectric function, the correlation and exchange interaction of the electron gas in solids is also taken into account. An analytical formula for the stopping power is obtained, and various theoretical results are compared with each other and with available experimental data.
