本文研究了辐射损伤对锆石结构变化的影响。通过模拟高能量反冲，我们观察到聚合，剪切变形，和晶胞膨胀，实验上看到的，并指出它们的起源。我们发现，损伤区的密度是非常不均匀的，增加从耗尽核心的致密边界。致密化的边界通过聚合相的产生而稳定。剪切变形和晶胞膨胀是由损伤与周围晶格的相互作用引起的。
We study the effects of radiation damage on structural changes in zircon. By simulating high-energy recoils, we observe polymerization, shear deformation, and unit-cell expansion, seen experimentally, and point to their origins. We find that the density of the damaged region is very nonuniform, increasing the from depleted core to the densified boundary. The densified boundary is stabilized by the creation of the polymerized phase. Shear deformation and unit-cell expansion arise from the interaction of the damage with the surrounding crystalline lattice.
