摘要：
The static properties and the dynamics of spherically symmetric 3-D particle clusters (Yukawa balls) are determined experimentally. For that purposed the stereoscopy with two standard video cameras as well as a three-camera high-speed system is used to simultaneously measure the positions of all particles in a Yukawa ball. The order phenomena, like shell configuration and occupation numbers, are found to be in agreement with the models and simulations. The normal modes' analysis for the Yukawa ball is presented.
