摘要
The electron momentum correlation after nonsequential double ionization of N-2 and O-2 in ultrashort light pulses at light intensities near 1.5x10(14) W/cm(2) has been investigated. The experimental results reveal distinctive differences between the molecular species and between molecules and atoms of similar ionization threshold. We provide evidence that recollision double ionization is the essential mechanism and trace the origin of the differences back to the symmetry of the orbitals occupied by the valence electrons.
