强飞秒硬X射线脉冲作用下的团簇动力学
Dynamics in a cluster under the influence of intense femtosecond hard x-ray pulses
摘要：
本文研究了小原子团簇在短（10-50 fs）强硬X射线（10 keV）脉冲中的行为。我们使用基于非相对论经典运动方程的数值模拟。通过各自的截面考虑量子过程。我们表明，有一个库仑爆炸，它有一个不同的动力学比发现在经典的激光驱动的集群爆炸。我们讨论了我们的结果的后果，单分子成像的自由电子激光脉冲。
英文摘要：
In this paper we examine the behavior of small cluster of atoms in a short (10-50 fs) very intense hard x-ray (10 keV) pulse. We use numerical modeling based on the non-relativistic classical equation of motion. Quantum processes are taken into account by the respective cross sections. We show that there is a Coulomb explosion, which has a different dynamics than one finds in classical laser driven cluster explosions. We discuss the consequences of our results to single molecule imaging by the free electron laser pulses.
