Abstract
The unoccupied electronic states of LaCoO3 and PrCoO3 are studied using room temperature inverse photoemission spectroscopy and ab initio GGA+U band structure calculations. A fairly good agreement between experiment and theory is obtained. The intensity of the peak just above the Fermi level is found to be very much sensitive to the hybridization of Co 3d and O 2p orbitals. Moreover, the band just above the Fermi level is of Co 3d character with little contribution from O 2p states.
