Figure 2.9.6.1
Calculated neutron reflectivity curves corresponding to the three density profiles in the inset (i.e. solid line in density profile corresponds to solid line in reflectivity plot). Note that in the density plots the solid and longdash curves coincide except at the oscillation on top of the plateau, whereas the solid and shortdashed curves coincide except at the trailing edge between 30 and 42 Å.
