- A resonant photoemission study has been performed for Pr1-xSrxMnO3 (x = 1/3,1/2) and the partial spectral weight (PSW) distributions of both Pr 4f and Mn 3d electrons have been determined. With varying temperature (T) and x, metal-insulator transitions are observed in the photoemission data. The Pr ions in Pr1-xSrxMnO3 are trivalent, and Pr 4f PSW exhibits a dominant hybridization peak indicating large Pr 4f-O 2p mixing. The Mn 3d PSW at low T shows a charge gap for x = 1/2, and a reduced spectral intensity near E-F for x = 1/3, suggesting the localized nature due to the lattice polaron formation.
