摘要：

High-energy ion scattering in combination with channeling has been used to study the W(001) + hydrogen surface. It is shown conclusively that the clean W(001) and the W(001)c(2×2)H surfaces are reconstructed at room temperature, that the surface reorders by H saturation, and that two models proposed for the c(2×2) surface structure are not valid. Furthermore we have obtained absolute coverage data [for the W(001) + D2 system] using a nuclear reaction technique. © 1979 The American Physical Society.
