Electronic structure studies of rare-earth intermetallics using Indus synchrotron

The ground state properties of rare-earth intermetallics depend on the nature of f-electrons and the strength of hybridization of the f-electrons with the delocalized band states present in the system. To understand the origin of various properties in these systems it is extremely important to probe the density of f-electrons experimentally. We have used the valence band photoelectron spectroscopy with a widely tunable photon energy to obtain the information about the density of f-electrons in the correlated systems like CeAg₂Ge₂ and EuCu₂Ge₂. I shall discuss some of these results in this talk. (author)
