Description: This paper presents results of resistivity and susceptibility measurements on CePd/sub 3/ and its alloys which support the existence of a third significant temperature, T* = 40K. Anomalous pressure dependence of rho(T) occurs and nonmagnetic impurities cause large increases in rho(T) on this scale, which is distinct from and smaller than the scale T/sub max/ over which coherence first appears. Evidence is given that the magnetic form factor anomaly known to exist in CePd/sub 3/ arises on the same scale T* suggesting that the 5d spin susceptibility which is responsible for the form factor anomaly is connected with the low temperature transport anomalies. The discussion is limited to the relationship of these results to other experimental measurements in CePd/sub 3/. In particular, we stress the relationship of these results to those of recent optical conductivity measurements which show that the quasi-particle effective mass is strongly renormalized at low temperatures. This occurs over a temperature scale proposed for T*.
