We have measured the Korringa contribution T1e to the nuclear spin lattice relaxation time of the interstitial 12B in noble metals. The Korringa product of 12B shows that the conduction-electron spin susceptibility is exchange enhanced similarly to that sensed by the matrix nucleus. The enhancement factors are equal within the experimental errors for both interstitial and matrix positions in Cu and Ag. The small difference of the enhancement factors in Au can be attributed to a probe effect.
