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 competition among various electronic transitions (neutralization through various channels, reionization, deexcitation, and reneutralization) which 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.
