| 摘 要： | 本文数值研究了阿秒分辨下双电子He原子发射高次谐波的特点. 数值计算结果表明, 双电子谐波光谱的截止能量与单电子相比有较大延伸, 并且我们发现了一些新的截止能量. 随后分析显示, 这些新的截止能量是由双电子的双回碰机制所导致的, 并且电子相关效应在里面起到了很重要的作用.

Double recombination for the two electron harmonic generation |
| |
| Abstract: | Attosecond-resolution two-electron harmonic generation from He atom has been investigated. It shows that two-electron harmonic exhibits an extended plateau and many new cutoffs beyond the classical single-electron cutoff. Further analyses show that these extended new cutoffs are caused by double recombination of the two electrons. Moreover, the electron-correlation effect plays an important role in these processes. |

| Keywords: | high-order harmonic generation (HHG) two-electron double recombination electron-correlation effect |
