Abstract

The two systems

c (2 \times 2) O / Cu (001)

and

(\sqrt{2} \times 2 \sqrt{2}) R 45 °

O/Cu(001) have been studied by normal photoelectron diffraction (NPD), with the use of

O (1 s)

line. In the

c (2 \times 2)

structure oxygen occupies the fourfold hollow site, with

d_{⊥} = 0.80 (5)

Å. The

\sqrt{2} \times 2 \sqrt{2}

structure has a similar NPD curve, indicating the same local site geometry for the

c (2 \times 2)

sublattice.
