The interaction of collision cascades initialized by alpha decays in PuO₂ crystals with xenon, helium and mixed Xe-He bubbles of linear dimensions of 1–2 nm was studied by a molecular dynamics technique. The bubbles were not destroyed by the cascades studied, however individual fast Xe and He atoms could be released. These fast atoms received high energies up to 90% of the collision cascade energy (80 keV). Also, the diffusion migration of helium atoms to the region of the crystal lattice damaged by the collision cascade was detected. Xenon atoms did not diffuse to the damage area on the simulated time scale. However, the xenon clusters changed their shape in the disordered surroundings.

通过分子动力学技术研究了PuO ₂晶体中氙原子，氦原子和线性尺寸为1-2 nm的混合Xe-He气泡的α衰减引发的碰撞级联的相互作用。所研究的级联并没有破坏气泡，但是可以释放出单独的快速Xe和He原子。这些快原子接受高达碰撞级联能量（80 keV）的90％的高能量。同样，检测到氦原子扩散迁移到被碰撞级联破坏的晶格区域。氙原子在模拟的时间尺度上没有扩散到损伤区域。但是，氙气簇在混乱的环境中改变了形状。
