摘要：

The high-resolution photoemission spectral profiles of the conduction bands of K3C60 and Rb3C60 recorded at 10 K exhibit fine structure not observed at higher temperatures. Calculations of the effects of electron-boson coupling in A3C60 within a simple model demonstrate that the features in the low-temperature photoemission spectral weight are consistent with satellites due to phonons and the charge-carrier plasmon. Possible causes of the observed temperature dependence of the conduction-band spectral weight are discussed.
