摘要：

Symmetry-resolved photoabsorption spectra of free N2 molecules in the K-shell excitation region have been obtained using a technique of angle-resolved photoion spectroscopy combined with linearly polarized undulator radiation. The obtained SIGMA- and PI-symmetry component spectra have nicely demonstrated the symmetry decomposition of the photoabsorption spectrum. These spectra have been compared with theoretical calculations in the photon-energy regions below and above the ionization threshold.
