Abstract
We present the results of analysis of the observed structure factors S(k) of liquid 4f rare earth metals. We have assumed a repulsive Yukawa potential as a convenient choice of reference potential, and have carried out the calculations within the mean spherical approximation (MSA). Our analysis only gives qualified support to the view that there is a hardening of the cores as the 4f-band is filled across the lanthanides for La to Lu.Keywords
