摘要：
The authors investigated the temperature dependence of the Knight shift, the shape of the NMR line and spin lattice and spin-spin relaxation times of nuclei **2**9Si in V//3Si. The experimental data show that d-electrons make a decisive contribution to the resonance parameters of **2**9Si. By comparing the NMR and susceptibility data, they found the polarization hyperfine magnetic field on nuclei **2**9Si, separated out the different kinds of contributions to the measured parameters and estimated the effects of electron-electron interaction. When T less than 60 K the hyperfine field distribution observed on nuclei is apparently associated with pre-transition structural distortions.
