The results of Raman spectroscopy and magnetic susceptibility measurements in the actinide compounds UO(2), UPt(3) and UBe(13) are presented. The differences in the degree of localisation of the 5f-electrons in the insulating UO(2) and in the metallic, heavy fermion compounds UPt(3) and UBe(13) are discussed. In both types of compounds there is evidence of localised electronic excitations which yield a good fit of the magnetic susceptibility data. The spin relaxation rates of UPt(3) and UBe(13) at q¸0 are determined experimentally from the quasielastic light scattering.
