Adsorbed structures of Ba on Si(1 1 1) surfaces have been observed by LEED. In elevating the annealing temperature after a few monolayers (MLs) deposition at room temperature (root3 x 2 root3)R30 degrees, 2 x 8 and 3 x 1 patterns were observed as reported by Weitering [H.H. Weltering, Surf. Sci. 355 (1996) L271]. Additionally a one-dimensional 10 x 1 pattern was observed in the temperature range between the appearance of two-dimensional 2 x 8 and 3 x 1 patterns. This pattern is considered to be produced by a combination of the periodical terrace with a width of 10 unit lengths separating each step and a 5 x 1 reconstruction on the terrace.
