Abstract

Elastic angular scattering spectra were obtained from pure and particle-seeded microdroplets, stably levitated in an electrodynamic trap. Both pure and seeded droplet spectra consist of broad interference peaks; however, in the seeded spectra, the peak amplitudes suffer random perturbations during sequentially captured spectral profiles. A simple model is developed suggesting that these perturbations result from random particle motions inside the droplet. The observed time scale of these perturbations provides an estimate of the corresponding particle diffusion length, which is compared with characteristic lengths in the droplet.
