摘要：

A new and unusual yield enhancement [(20-30)% above Rutherford] has been observed in the energy spectra for He+ backscattering to 180° 0.25°in the energy range 0.2 MeV<E<2.5 MeV for a variety of amorphous and polycrystalline targets. The depth and angular dependence of the yield enhancement has been established for a variety of materials and experimental conditions. Several possible explanations are discussed. © 1983 The American Physical Society.
