软碰撞是激光驱动的电子与其母离子的远距离碰撞。这种碰撞可能会导致能量聚束，因为具有不同初始漂移动量的电子可以获得恰好抵消这些差异的脉冲。聚束在光电子谱中产生一系列峰。我们将表明，这一系列可以通过增加持续时间的相位稳定的几个周期的脉冲，通过实验被揭露的峰值。
Soft recollisions are laser-driven distant collisions of an electron with its parent ion. Such collisions may cause an energy bunching, since electrons with different initial drift momenta can acquire impulses which exactly counterbalance these differences. The bunching generates a series of peaks in the photo-electron spectrum. We will show that this series could be uncovered peak by peak experimentally by means of phase-stabilized few-cycle pulses with increasing duration.
