首次实验研究球形三维等离子体晶体组成的数百或数千微米大小的聚合物颗粒悬浮在射频气体放电。这些“库仑球”不受无尘区域（空隙）形成的影响，并具有嵌套晶体壳的不寻常结构。当小系统处于固相时，大系统显示熔化效应。
First experimental investigations of spherical three-dimensional plasma crystals consisting of hundreds or thousands of micrometer-sized polymer particles suspended in a radio-frequency gas discharge are described. These "Coulomb balls" are not subject to the formation of dust-free regions (voids) and have an unusual structure of nested crystalline shells. While small systems are in a solid phase, large systems show melting effects.
