Two-peak energy distributions of secondary ions sputtered from the surface of an aluminum single crystal
Kosyachkov A. A.
Two-peak energy distributions have been observed for the secondary-emission ions from the surface of an Al(OOl) single crystal. The mechanism shaping these distributions is discussed. A focusing of the energy of a cascade of atomic collisions in an ordered crystal lattice is taken into account. The point defects caused in the surface by ion bombardment are also taken into account.
