Angular Laws of Dispersion and Ion-Electron Emission at Greater Ion Target Incidence Angles

摘要

The angular dependences of ion-electron emission in polycrystalline copper, tungsten, nickel, and molybdenum flakes are measured. The incidence angles of ions on the target varied in the intervals from 60 to 82-86 degrees. Measurement accuracy is a =7%. From the derived results it is concluded that the presence of maxima on curves of angular dependence of dispersion coefficients is connected with the displaced atoms of the lattice, which do not participate in the process of formation of secondary electrons.
