  The Mn L_2,L_3 x-ray spectra of the Cu_2MnAl and Co_2MnZ (Z=Al,Ga, Sn, Sb)
Heusler alloys have been investigated by the Resonant X-ray Emission
Spectroscopy (RXES) using linearly polarized monochromatic synchrotron
radiation for. The interplay between the half-metallic character of the Mn 3d
electronic structure in connection with the local magnetic moment $\mu_{Mn}$
and Mn $2p\to 3d$ x-ray emission spectra is discussed.
