A recent, major, puzzle in the core-level photoemission spectra of dopedmanganites is the observation of a 1-2 eV wide shoulder with intensity varyingwith temperature T as the square of the magnetization over a T scale of order200K, an order of magnitude less than electronic energies. This is addressedand resolved here, by extending a recently proposed two electron fluid l-bmodel for these systems to include core-hole effects. The shoulder arises froma rapid redistribution of e_g electron density, as a function of T, between thehighly localized (l) and band-like (b) states. Furthermore, our theory leads toa correspondence between spectral changes due to increasing doping anddecreasing T, as experimentally observed.
