摘要：

The formation of macroscopic ordered structures in the standing striations of a stationary glow discharge in Ne is observed. A Coulomb quasicrystal is formed by spherical glass particles with diameters of 50-63 mu m and charge Zp similar to 7 similar to 10(5) e. The interparticle distance is approximately 300 mu m. This corresponds to a nonideality parameter Gamma similar to 5 similar to 10(4), which leads to crystallization in the Yukawa model. The factors leading to the formation of a quasicrystal in the striations are discussed. (C) 1996 American Institute of Physics.
