The so-called shake-up satellites accompanying C1, photoionization in Cm have been studied theoretically by means of INDO/CI. It is found that the lowest shake-up satellites in Cm correspond to global charge-transfer excitations that move charge from the opposite side of the fullerene cage to the core-hole region, whereas higher-energy satellites tend to move charge from regions nearer to the core hole. Analogies are drawn, with, on the one hand, smaller model molecules such as napthalene and acenaphtylene and, on the other hand, infinite systems such as graphite. 0 1994
