利用角分辨光离子谱技术结合线偏振波荡器辐射，获得了自由N2分子在K壳层激发区的“对称分辨”光吸收谱.所得到的光吸收谱的对称性分解很好地证明了光吸收谱的对称性分解。这些光谱进行了比较与理论计算中的光子能量区域低于和高于电离阈值。
‘‘Symmetry-resolved’’photoabsorption spectra of free N 2 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 Σ-and Π-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.
