Liquid structure for the 3d transition metals near melting is investig
ated using the linearized Weeks-Chandler-Andersen (LWCA) theory. Here
the effective interionic pair potential is described by the Wills-Harr
ison model. Results show that LWCA predicts the structure factor much
better than that of WCA. Results also show that in the middle of the 3
d series LWCA predicts reasonable liquid structure where the WCA-ORPA
has been unsuccessful.
