    Abstract

    A new method for determining the lattice parameter using atomic beam diffraction is described. Using this method, we have measured the temperature dependence of the lattice parameter of LiF(001). It was found that the value of the surface thermal expansion coefficient is higher by a factor of 3.6 than the bulk value for temperatures up to 180°C.
