Acceleration of convoy electrons produced by MeV He ions for glancing angle scattering from a clean surface
Abstract
Dependences of the most probable energy of convoy electrons ontheergy of MeV H and He ions are studied for glancing angle scattering of the ions from a clean (001) surface of SnTe. The convoy electrons emitted at He scattering are faster than the projectile He ions, while at H scattering they are almost isotachic to the projectile H ions. The acceleration of convoy electrons at He scattering is explained as the result of polarization of valence electrons induced by the projectile He ion.
