离子碰撞诱导液滴多重碎裂
Ion-impact-induced multifragmentation of liquid droplets
摘要：
探讨了高能离子穿越液滴的不稳定性。这种不稳定性是由离子引起的预期冲击波引起的。建议观察具有高线性能量转移的离子穿过的小液滴的多重碎裂，以证明冲击波的存在。一些影响进行了分析，努力找到这样一个实验的条件是显着的。冲击波的存在至关重要地影响离子辐射损伤的情况，因为冲击波显著地促进生物分子的热机械损伤以及活性物质的运输。虽然生物实验的分析支持了这一假设，但冲击波尚未被直接观察到，尽管在会议上交换了一些检测它们的实验想法。
英文摘要：
An instability of a liquid droplet traversed by an energetic ion is explored. This instability is brought about by the predicted shock wave induced by the ion. An observation of multifragmentation of small droplets traversed by ions with high linear energy transfer is suggested to demonstrate the existence of shock waves. A number of effects are analysed in effort to find the conditions for such an experiment to be signifying. The presence of shock waves crucially affects the scenario of radiation damage with ions since the shock waves significantly contribute to the thermomechanical damage of biomolecules as well as the transport of reactive species. While the scenario has been upheld by analyses of biological experiments, the shock waves have not yet been observed directly, regardless of a number of ideas of experiments to detect them were exchanged at conferences.
