Photoemission spectra of NiAs-type manganese pnictides, MnAs and MnSb, are studied theoretically on the basis of their electronic band structures calculated using the full-potential linearized augmented-plane-wave method. The valence-band photoemission spectra are calculated from the partial density of states projected on each orbital component of constituent atoms by taking account of the photoionization cross-sections, the lifetime broadening and the instrumental resolution. A prominent peak structure arising from the Mn 3d majority-spin states is found at about 2 eV below the Fermi level in the photoemission spectra obtained for both MnAs and MnSb. The results are compared with recent observations and discussed in connection with the validity of the band-structure calculations.
