    "abstract": "Small three-dimensional strongly coupled charged particles in a spherical\nconfinement potential arrange themselves in a nested shell structure. By means\nof experiments, computer simulations and theoretical analysis, it is shown that\ntheir structural properties depend on the type of interparticle forces. Using\nan isotropic Yukawa interaction, quantitative agreement for shell radii and\noccupation is obtained.",
