摘要：

We have determined absolute coverages of deuterium on Cu(100) using the reaction D(He-3, p)He-4 and found a saturation coverage of one deuterium atom per surface copper atom. LEED observations reveal no superlattice structures below approximately 0.45 ML and four different superlattice structures above this coverage.
