Fig. 64: 

a) Temporal evolution of the angular distribution of the diffracted intensity during growth of Ag(100) at 313 K. The deposition time and the corresponding coverages are indicated. The different curves are not drawn to the same scale. Each profile was recorded in 3.5 seconds. The units of the horizontal axis are reciprocal space co-ordinates. The continuous lines are lorentzian fits to the data. Note the resolution of the measurements: the central and broad components of the profile at t = 19 seconds are separated by 0.016 reciprocal lattice units.

b) Temporal evolution of the intensities of the central peak (bottom) and diffuse peaks (top). Note the different ordinate scales. The continuous lines are fits using a theoretical model based on rate equations.
