    Emission of electrons from Al(100) during bombardment by 50-520 eV Li+ ions was measured as a function of incident ion energy and direction. The process was modeled by a surface electron-hole pair excitation mechanism and was quantified with a one-electron parametric theory. This is a previously unidentified mechanism which is characterized by a strong dependence on the energy and angle of incidence of the primary particle.

    Emise elektronů z Al(100) během bombardování 50-520 eV Li ionty byla měřena jako funkce energie iontů a jejich úhlu dopadu. Process byl modelován povrchovým elektron-děrovým excitačním mechanismem a byl quantifikován pomocí jedno-elektronové parametrické teorie. Tento dosud neindetifikovaný mechanism je charakterizován silnou závislostí na energii a úhlu dopadu primární částic.
