本文报道了氩在394 nm强场双电离中电子能量分布的离散结构。实验条件的选择是为了保证两个电子的非顺序弹射和中间的重散射步骤。我们在两个电子的能量总和中发现了离散的超过阈值的电离峰，正如所有量子力学计算所预测的那样。然而，更令人惊讶的是，在单个电子的能量分布中观察到两个高于阈值的电离梳。
We report on the observation of discrete structures in the electron energy distribution for strong field double ionization of argon at 394 nm. The experimental conditions were chosen in order to ensure a nonsequential ejection of both electrons with an intermediate rescattering step. We have found discrete above-threshold ionization like peaks in the sum energy of both electrons, as predicted by all quantum mechanical calculations. More surprisingly, however, is the observation of two above-threshold ionization combs in the energy distribution of the individual electrons.
