We have remeasured the Korringa contribution T1e to the nuclear spin lattice relaxation time of the interstitial12B in nobel metals and in Al. The T1eT times the squared Knight shift K of12B taken from the literature, that is the Korringa product of12B, 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 enhancement factors at the boron and at the matrix position are different in Au and Al.
