V51Knight Shift in theV3Si Type of Compounds in the Normal State

Gossard has observed in ${\mathrm{V}}_3$Si the effect on the ${\mathrm{V}}^{51}$ Knight shift of the low-temperature structural transformation discovered by Batterman and Barrett. This effect can be explained in a simple model which assumes a fine $d$-band structure close to the Fermi level. This model has already given a fairly good explanation of the low-temperature lattice instability in the normal state.
