On the Velocity Dependences of Secondary Ion Emission from Metallic Surfaces

We have examined the various fundamental issues that are important for the accurate determination of the ionization probability as a function of the emission velocity. The different surface potentials encountered by the sputtered neutral atoms and the secondary ions respectively result in corrections to both the trajectories of the secondary ions and the phase space covered by the detector. © 1989, Taylor & Francis Group, LLC.
