Scattering results for an uncoated PS sphere. (a) A representative scattering pattern. The color bar indicates the log10 photon count per pixel accumulated over 20 s. (b) A selection of azimuthally integrated scattering patterns, multiplied by q4 to emphasize the Porod character of the scattering. One can see that the spatial period of the intensity oscillations increases with the accumulated exposure times, meaning that the sphere radius decreases. Each curve has been offset by a factor of ten for visibility. (c) Radius of the PS sphere as a function of accumulated exposure time. The decrease of the radius is well described as a linear function of time. (d) Scattered intensity in the forward direction. The scattered intensity was found by fitting the form factor of a perfect sphere to the experimental data. One can see that the scattered intensity falls for increasing absorbed dose, consistent with having less material scattering.
