• N-2 valance orbitals
• electron momentum spectroscopy
• electron correlation effect

Detailed and accurate EMS measurements of complete valence region of N-2 molecule using a high resolution (Delta E = 0.8 eV, Delta p approximate to 0.1 a.u.) high efficiency electron momentum spectrometer have been performed. Several ionization peaks attributed to inner valence orbitals and correlation (satellite) states are resolved for the first time in the binding energy spectroscopy. By comparing the (e, 2e) cross sections of valence orbitals and the correlations states, significant insights into the dominant character of the valence and correlation states of N-2 are obtained. The EMS momentum distributions show that they provide a sensitive test for orbital wavefunctions from different theoretical models.
