Figure 4
The distribution of the scattering intensity as a function of the incident angle () of the impinging neutrons and the distance from the scattering plane (scattering depth) for the PEG microgel (a) and PNIPAM brush (b) is mapped. Intensity is simulated according to equation (3). Zero marks the scattering plane; values above refer to positions inside the silicon subphase. The white dotted lines approximately separate evanescent wave (EW) and transmitted (TS) intensities. |
