  The temperature dependence of the frequency shift and spin-lattice relaxation
rate of isolated, nonmagnetic Li-8 impurities implanted in a nearly
ferromagnetic host (Pd) are measured by means of beta-detected nuclear magnetic
resonance (b-NMR). The shift is negative, very large and increases
monotonically with decreasing T in proportion to the bulk susceptibility of Pd
for T > T*~ 100 K. Below T*, an additional shift occurs which we attribute to
the response of Pd to the defect. The relaxation rate is much slower than
expected for the large shift and is linear with T below T*, showing no sign of
additional relaxation mechanisms associated with the defect.
