Ion energy-angle distribution
WebIon scattering energy. The equation shows how the energy of a scattered ion peak is related to the other relevant factors. E S = Kinetic energy of the scattered ion M 1 = Relative atomic mass of the scattered ion E 0 = Kinetic energy of the primary ion beam M 2 = Relative atomic mass of the scattering surface atom θ = Scattering angle Web5 ION ENERGY DISTRIBUTION FUNCTION energies. Of course, changing the pressure results in a change in the discharge characteristics which may alter the shape and magnitude of the IEDF in a nonlinear way.
