The Mn Lα and Lβ spectra of Mn, MnO, Mn

have been measured. Each Mn La spectrum has been deconvoluted into two bands, Lα

and Lα

, and the integrated Lα

/Lα
B
intensity ratio was found to be inversely proportional to the Mn-0 inter-atomic distance, but proportional to the oxidation number. This finding tends to indicate the likelihood of crossover transition from oxygen to manganese. The intensity ratio Lβ/Lα
B
of the pure metal was found to coincide closely with the statistically predicted value of 0.5. Furthermore, for Mn-metal, as well as for the oxides, the shift of the Lα
A
band from the Lα
B
band was found to agree with the change in the Lβ/Lα peak intensity ratio as a function of oxidation number.
