Abstract: | ESCA spectra of the Th 4d, 4f, 5s, 5p and 5d core levels have been recorded in ThF4, Th(AcAc)4 and other Th complexes. In addition to weak 4f and 5d satellites which are normally considered to be shake up satellites, a number of unusual satellites have been characterized in these compounds. In particular, the intense 5p3/2 satellites, as well as previous similar 5p satellites in other actinides, are shown to be due to configuration interaction of the 5p hole state with a 5d2 hole state. Similarly, the 4d, 5s and additional 5d satellites are probably also due to configuration interaction. |
