Partial and total electronic stopping cross sections of solids and atoms for protons are estimated by the recently developed wave packet theory and the Lindhard theory. The wavepacket theory presents the one‐shell dielectric function for the bound electrons (BE's) in the framework of RPA by adopting the momentum space representation, where the BE's are treated as an interacting electron gas. Numerical estimation of the stoppings are performed over a wide specific energy range, i.e., 1 to 10 4 keV/amu, on the basis of the independent shell model. The oscillatory behavior of the stopping cross sections are also shown with respect to target atomic number. The calculated results are in good agreement with the data.
