摘要

我们探索了轻原子粒子高速（但尚未达到相对论）碰撞中的电离机制，其中一个粒子最初处于激发的内部状态。该机制由广义布赖特相互作用驱动，通过碰撞粒子之间的辐射能量传输进行，其传输距离极长。将这一机制与高速碰撞的 "标准 "机制进行比较后发现，它在与激发目标原子的碰撞中可以发挥明显的作用。

Ionization by radiative energy transport vs. impact ionization in energetic atomic collisions

We explore a mechanism for ionization in high-velocity (but not yet relativistic) collisions of light atomic particles, one of which being initially in an excited internal state. This mechanism is driven by the generalized Breit interaction and proceeds via radiative energy transport between the colliding particles which has an extremely long range. A comparison of this mechanism with those which are ‘standard’ for high-velocity collisions shows that it can play a noticeable role in collisions with excited target atoms.

期刊介绍： Published twice-monthly (24 issues per year), Journal of Physics B: Atomic, Molecular and Optical Physics covers the study of atoms, ions, molecules and clusters, and their structure and interactions with particles, photons or fields. The journal also publishes articles dealing with those aspects of spectroscopy, quantum optics and non-linear optics, laser physics, astrophysics, plasma physics, chemical physics, optical cooling and trapping and other investigations where the objects of study are the elementary atomic, ionic or molecular properties of processes.
