Electronic structures of gallium and indium across the solid-liquid transition

Electronic structures of gallium and indium in the solid and liquid states have been investigated using photoemission and bremsstrahlung isochromat spectroscopies yielding information concerning the occupied and unoccupied parts of the density of states. Experimental results are compared with various calculations in order to obtain a detailed description. X-ray photoemission spectra of Ga 2p and In 3d core levels exhibit shifts across the solid-liquid transition, arising from changes in screening.
