Abstract:	Measurements of the specific heat jump ΔC at the superconducting critical temperature T_c on ( $Th, Sc$ )Ce and ( $Th, Y$ )Ce Ce impurity, solid solution alloy systems indicate that the former systems obey the BCS law of corresponding states (LCS) characteristic of superconductors with non-magnetic impurities while the latter systems present deviations from the LCS linear relation between reduced parameters which are attributed to the development of localized moments at the Ce ions as the Y concentration increases.
