  An exposure of a cleaved MgO(001) surface to water generates hydroxyl (OH) and/or magnesium hydroxide (Mg(OH)<sub>2</sub>) on the MgO surface. We prepared OH or Mg(OH)<sub>2</sub> rich surface by different dose of water. The change of the surface composition (MgO, OH, Mg(OH)<sub>2</sub>) by heating (room temperature ~200°C) was investigated with O1s spectra by X-ray photoelectron spectroscopy. The samples were heated by baking the vacuum chamber. In hydroxyl surface the OH component reduced to about 30% after the heating of 200°C. On the other hand, in Mg(OH)<sub>2</sub> rich surface, the Mg(OH)<sub>2</sub> component did not change by same thermal treatment.<br>
