The effects of dilute Zn impurities on the uniform magnetic susceptibility
are calculated in the normal metallic state for a model of the spin
fluctuations of the layered cuprates. It is shown that scatterings from
extended impurity potentials can lead to a coupling of the q~(pi,pi) and the
q~0 components of the magnetic susceptibility chi(q). Within the presence of
antiferromagnetic correlations, this coupling can enhance the uniform
susceptibility. The implications of this result for the experimental data on Zn
substituted YBa2Cu3O{7-delta} are discussed.Comment: 4 pages, 4 figure
