X射线离镜漫散射被用来直接探测F（CF 2）（10）（CH 2）（2）OH在己烷-水界面上吸附的单分子膜中畴的统计分布。这些领域出现非常接近从单层固体到气相的过渡。该域具有近似1.5 μ m的几乎恒定的半径和随温度从2到8 μ m变化的最近邻分离。磁畴具有平衡尺寸的证据表明，可以确定磁畴线张力，λ（t）约为3 × 10（-11）N。
X-ray off-specular diffuse scattering is used to directly probe the statistical distribution of domains in monolayers of F(CF2)(10)(CH2)(2)OH 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 approximate to 1.5 mum and a nearest-neighbor separation that varies from 2 to 8 mum with temperature. Evidence that the domains are of equilibrium size suggests that the domain line tension, lambda(t) approximate to 3 x 10(-11) N, can be determined.
