Abstract
We present infrared reflectivity measurements of the rare-earth nickel ates PrNiO3 and NdNiO3 between 30 and 5000 cm(-1) at temperatures betw een 15 and 300 K. We observe a dramatic change of the spectra from met allic-like to nearly insulating in a narrow range of temperatures belo w the metal-insulator transition.
