在长度和速度计中对N2进行分子强场近似计算，得到光电子角分布、总电离率和离子信号作为激光场与分子之间取向的函数。我们的研究补充了分子隧穿计算，其结果与实验结果和长度规分子强场近似结果在定性上是一致的。
Molecular strong-field approximation calculations in the length and velocity gauges are performed on N2 to produce photoelectron angular distributions, total ionization rates and ion signals as a function of the orientation between the laser field and the molecule. Our study is supplemented by molecular tunnelling calculations, the results of which are in qualitative agreement with the experimental findings and the length gauge molecular strong-field approximation results.
