Adsorption and desorption of water on well-ordered and sputter-damaged single crystal MgO(100) surfaces were studied by a combination of molecular beam reflection and temperature programmed desorption techniques. Adsorption exhibits precursor-mediated kinetics and desorption exhibits a strong dependence on substrate treatment, demonstrating the importance of surface defects. {copyright} {ital 1996 American Institute of Physics.}
