Figure 6
Phase-map analysis of the amplitude A(q) of the wave scattered by a nanoparticle. The inset displays the nanoparticle overlaid with ϕθ(x, y, z) for the particular value q = 0.042 Å−1, corresponding to ≃ 150 Å. Each slice of the particle (numbered 1 to 5) is assigned a complex number with phase ϕ and modulus |a| proportional to the slice volume. The amplitude of the scattered wave (in red) is obtained by adding the contributions of all slices, as in equation (5). |
