Popis:	Li− formation is studied by scattering a Li+ beam from a cesium covered tungsten (110) surface. The primary energy ranges from 1000 to 3000 eV. The measurements show that variation of the velocity component of the scattered particles parallel to the surface, can either enhance or decrease the Li− formation probability. The sign of this parallel velocity effect depends on the value of the normal velocity component. The experimental results are qualitatively explained by a semi-classical model.
