LOW-ENERGY STRUCTURAL FEATURES ON THE ENERGY-DEPENDENCE OF THE CURRENT OF IONS REFLECTED FROM A SOLID-SURFACE

Various structural features on the energy dependence of the current of ions reflected from a solid surface are analyzed. Structural features of three types (LAMBDA, V, and h) are predicted to result from a comp etition among various electronic transitions (neutralization through v arious channels, reionization, deexcitation, and reneutralization) whi ch accompany the motion of an atomic particle. Some new spectroscopic possibilities in experiments on the neutralization of low-energy ions (E < 200 eV) near a solid surface are discussed.
