  Using the recently developed version of the GW method employing the one-site
approximation and self-consistent quasiparticle basis set we calculated the
electronic structure of 3d and 4d transition metals at experimental atomic
volumes. The results are compared with traditional local density approach and
with experimental XPS and BIS spectra. Our results indicate that this technique
can be used as a practical starting point for more sophisticated many-body
studies of realistic electronic structures.
