We report here highly resolved photoelectron spectra of the outer- and inner-valence shells of NH3, together with the corresponding angular distribution parameter. The measurements were made in the 20–80 eV photon energy range, using synchrotron radiation as an ionizing source. In the inner-valence region, three spectral features were evidenced, and namely a main component at 27.4 eV and two weaker features at 31.4 and 35.4 eV. The spectral feature at 35.4 eV was not evident in the previous (e, 2e) measurements. Our experimental findings are compared with three different sets of calculations performed by the Green's function method. The best agreement is found with one of them which predicts three main lines and some low-intensity components. From the angular distribution measurements, we conclude that the nature of the spectral feature at 31.4 eV is different from the one of the main component at 27.4 eV.
