Abstract
While at intermediate reduced energies of about 10 −2 ≲ ϵ ≲ 1 a nearly universal relation of reduced ranges, ρ= f( ϵ), holds, the situation is different at low energies of about ϵ ≲ 10 −2. Here both projectile and target individualities may show up depending on their combinations. In homopolar materials, such as semiconductors, an oscillatory dependence of ρ on Z 1 has been reported previously; in metallic targets, however, this Z 1-effect is quenched. In ionic solids, an additional stopping mechanism, due to the Coulomb interaction of projectile ions with ionic lattice constituents, can appear as theoretically predicted. A review of these effects will be given with particular emphasis on the latter phenomenon.
