In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of Co3+ to one of the excited electronic levels at 650 ± 50 meV. We propose to perform measurements with higher incident energies up to 2.5 eV to confirm that this excitation is magnetic in origin, and to search for transitions at higher energies which are predicted by a model for localized Co3+ in LaCoO3. Observation of these levels would allow us to refine a model for Co3+ and, in particular, to identify the nature of the spin state transition which occurs on warming this canonical transition metal oxide compound above about 100 K.
