Figure 3.

Neutron in-plane scattering of a sandwiched sample of P/L = 1/50 under three conditions: equilibrated at 100% RH D2O (triangles), equilibrated with excessive D2O in a swollen state (circles), and equilibrated with excessive H2O in a swollen state (squares). Inset: Obtained from the circles curve after removing the background (the empty sample cell). The shoulder peak was fit with a Gaussian curve (gray) at 0.085 Å−1.
