The growth mode of Ag atoms on the W(110) plane has been studied using LEED and Low Energy Ion Scattering Spectroscopy (ISS). We find that Ag atoms grow in SK mode after annealing at 700 degrees C for the coverage similar to 3.0 ML. The grown three-dimensional Ag islands have the (111) plane surface. The (110) direction of the Ag islands is rotated 4.4 degrees from (001) direction of the W(110) surface. Using the ISS technique the surface structure of the two-dimensional Ag islands is investigated. The Ag adsorption height measured from the first layer of the W(110) surface is found to be 2.79 angstrom.
