摘要：

We study the temperature dependence in the photoernission spectra of A(3)C(60). To this end, we employ a model which takes account of both the electron-electron and electron-phonon interactions and calculate the photoemission spectra of a C-60(3-) molecule in a particle bath at finite temperature. We find that the change of the statistical weights of C-60(2-), C-60(3-) and C-60(4-) strongly affect the photoemission spectra,. Our result is in agreement with the observed temperature dependence of the photoemission spectra of A(3)C(60).
