X-ray off-specular diffuse scattering is used to directly probe
the statistical distribution of domains in monolayers of
adsorbed at the hexane-water interface.
These domains appear very near a transition from a monolayer solid
to gas phase. The domains have a nearly constant radius of
and a nearest-neighbor separation that
varies from 2 to 8 with temperature. Evidence that
the domains are of equilibrium size suggests that the domain line
tension, 
, can be
determined.
