We study the electronic structure of single-crystal ${\mathrm{Tb}}_{0.5}{\mathrm{Sr}}_{0.5}{\mathrm{MnO}}_{3}$, a non-charge-ordered mixed-valent semiconductor which exhibits glassy magnetic ground state. use techniques soft x-ray photoemission, hard absorption, and resonant photoemission spectroscopy to investigate occupied unoccupied states ${\mathrm{Tb}}_{0.5}{\mathrm{Sr}}_{0.5}{\mathrm{MnO}...
