Elemental manganese has been studied by x-ray photoelectron spectroscopy. MgKαand ZrLαradiations were used as excitation sources for the study. In the literature a range of values has been reported for Mn core levels using Mg radiation. The purpose of this study is to provide spectral data obtained using Zr x-ray source in comparison with that obtained using Mg source. Such a data set will serve as a source of additional valuable information for enhancing the capability of x-ray photoelectron spectroscopy for investigating different specimens containing Mn. The XPS data in the 2pand 3pregions are presented. Significant differences are observed in the two sets of data. The data obtained using Zr source show considerable broadening of the core level spectra of Mn.
