The electron self-energy of the t1u states in A₃C₆₀ (A=K, Rb) is calculated using the so-called GW approximation. The calculation is performed within a model which considers the t_lu charge-carrier plasmon at 0.5 eV and takes into account scattering of the electrons within the tlu band. A moderate reduction (35%) of the tlu band width is obtained.
