Component of the cluster-induced force due to the hole screening. Component of the cluster-induced force acting on the moving electron due to the dynamic screening of the hole by the electronic charge of the cluster, <a onClick="popup('','MathML',630,470);return false;" target="_blank" href="">View MathML</a>. Results are shown as a function of the electron position for jellium clusters (rs = 4) of different size comprising N = 20, 58, 106, and 556 electrons. Electron velocities are (a) υ = 1 a.u, (b) υ = 2.5 a.u. Vertical dashed lines correspond to the radii of the clusters.
