N2 - Valence-band and conduction-band structures of NiAs-type MnTe have been investigated by means of ultraviolet photoemission and inverse-photoemmion epectroscopies. Based on the comparison with the results of band-theory, features observed at -3.7 and 2.9 eV relative to the valence-band maximum (VBM) are assigned to emission from the Mn 3d↑ and 3d↓ states with fairly localized character, providing a spin-exchange splitting energy of 6.6 ± 0.2 eV. On the other hand, the Mn 3d photoemission and inverse-photoemission spectra have been calculated in terms of a configuration interaction theory using a MnTe6 model cluster, to interpret the whole features of the experimental spectra including multielectron satellites. The Mn 3d spectral features at -12 to -6, -6 ∼ 0 and 2.9eV relative to the VBM are attributed predominantly to transitions into the d4, d5 L and d6 final state configurations, respectively, where L represents a ligand hole.
