Nuclear magnetic resonance in dilute alloys of lithium

Abstract

Both the change in Knight shift with concentration and the quadrupole broadening of the magnetic resonance of the 7L1 nucleus in a series of dilute lithium alloys has been investigated. An attempt is made to correlate both sets of experimental data in the terms of Friedel's model of the scattering of electrons at the Fermi surface. It is shown that a set of phase shifts chosen empirically to give the experimental Knight shift also accounts satisfactorily for the residual resistivity and the quadrupolar broadened line shapes.
