Figure 6
Calculation of the change of the scattering yield (modulus) owing to a thin sheet of vapor forming around a gold particle (red line, 2 nm vapor thickness on a 38 nm particle) compared with the signal-to-noise ratio limit owing to the shot noise (grey shaded area). The black line (uppermost curve) represents the full scattering of an ideal sphere, while the circles show the modulus of measured data of a 6 nm vapor layer on the ensemble of particles. |
