Angular dependence of electron emission induced by grazing-ion-surface collisions
Field-distorted wave (FDW) approximations were used for investigating the angle and energy distributions of electrons emitted during the grazing scattering of fast protons on an aluminum surface. The method was found to be consistent to deal with the electron emission from metal surfaces. Atomic inn...
