When 0.7 ML of Ba atoms are adsorbed on Si(001) at room temperature, the first preferential site of adsorption is T3 site with a height of 3.00 +/- 0.05 Angstrom from the second layer of Si(001) even though the periodicity is poor. The next favorable site is HH site with a height of 3.50 +/- 0.05 Angstrom from the second layer of Si(001). (C) 2001 Published by Elsevier Science B.V.
