用分子动力学方法研究了单组分等离子体，模拟了重离子储存环中带电粒子的行为。所使用的哈密顿量限制了等离子体在与束一起移动的参考系中的环中的行进方向的横向方向上。结果表明，一个意想不到的分层密度在横向方向上，和一个倾向于第一邻居协调14（8+6）似乎开始。在每个壳层上，我们观察到粒子排列的三角形图案。
A one-component plasma has been studied by molecular-dynamics calculations to simulate the behavior of charged particles in heavy-ion storage rings. The Hamiltonian used confines the plasma in the directions lateral to the direction of travel in the ring in the frame of reference which is moving with the beam. The results show an unexpected stratification of density in the lateral direction, and a tendency towards a first-neighbor coordination of 14 (8+6) seems incipient. On each shell we observe a triangular pattern of particle arrangement.
