X-Ray Kβ Emission Spectra of Metallic Manganese, MnO, MnP and α-MnS

Abstract

X-ray Mn Kβ emission spectra of metallic manganese, MnO, MnP and α-MnS are obtained by fluorescent excitation method. A two-crystal spectrometer is used in the (1, 1) position. The Mn Kβ emission spectrum consists of a diagram line Kβ_1,3, a valence band Kβ₅, a non-diagram line Kβ′, etc. The general features of the Mn Kβ spectra of metallic manganese and MnP resemble each other and those of MnO and α-MnS are alike. According to Tsutsumi the origin of the Kβ′ line is derived from the exchange interaction between the electrons of the incomplete 3d shell of 3d elements and the hole of the 3p shell owing to the emission of the Kβ_1,3 line, and thus some correlation is expected between the features of the Kβ′ line and the Kβ₅ band. Results show the correlation between them and also support the fact that MnP has metallic character.
