摘要：

Molecular strong-field approximation calculations in the length and velocity gauges are performed on N-2 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.
