标题： Dynamics of correlated transfer-ionization in collisions with a fast highly charged ion

摘要： 裸离子与原子之间的快速碰撞中的转移电离现象，即其中一个原子电子被捕获而另一个被发射出去的过程，关键依赖于动态的电子-电子关联。 我们表明，在与高度带电离子的碰撞中，离子的强场对转移电离的相关通道有着非常显著的影响。 具体来说，该场减弱了电子向与离子运动方向相反的方向发射，并且强烈抑制了垂直于此运动方向的发射。 相反，电子发射被重新导向到动量空间中那些在与低电荷离子的快速碰撞中很少被占据的部分。 显示英文摘要

摘要： Transfer-ionization in fast collisions between a bare ion and an atom, in which one of the atomic electrons is captured by the ion whereas another one is emitted, crucially depends on dynamic electron-electron correlations. We show that in collisions with a highly charged ion a strong field of the ion has a very profound effect on the correlated channels of transfer-ionization. In particular, this field weakens electron emission into the direction opposite to the motion of the ion and strongly suppresses the emission perpendicular to this motion. Instead, electron emission is redirected into those parts of the momentum space which are very weakly populated in fast collisions with low charged ions.
