Plots of neutral fractions for Li+ scattering on Au (111), Cu (111), and Ag (111) versus perpendicular exit velocity. The incident angle with respect to the surface plane is 24° and the exit angle is 90°. Experiment:[20] (▲) Ag (111), (◼) Au (111), (●) Cu (111). Theory: the blue dotted line represents the jellium model results for Cu (111) enlarged by 100;[20] the green dashed-dotted line denotes the jellium model results for Ag (111);[20] the red solid, black, and purple dashed lines refer to the calculated results using the BN model, respectively.
