Resistivity, LIII absorption, and X-ray diffraction have been made on several alloys of the form Ce1-xThxCu2Si2 and the related system Ce1-xThxNi2Si2. In the Cu-based compounds the transport measurements indicate that the Kondo effect is substantially quenched with increasing Th substitution. In both the Cu and Ni based alloys LIII absorption measurements of Ce show a decrease of the Ce valence with Th substitution. These results are in accord with the action of Th substitution in other Ce intermetallic compounds, however, they stand in contrast to the action of Th in elemental Ce.
