摘要：

The sudden photohole of least energy created in the photoemission process is a vibrationally excited state of a small polaron. Therefore the photoemission spectrum in LaMnO3 is predicted to have multiple Franck-Condon vibrational sidebands. This generates an intrinsic fine broadening approximate to0.5 eV. The photoemission spectral function has two peaks whose central energies disperse with bandwidth approximate to1.2 eV. Signatures of these phenomena are predicted to appear in angle-resolved photoemission spectra.
