The Knight shift, quadrupole interaction, spin‐lattice, and spin‐spin relaxation times for 51 V and magnetic susceptibility are measured as functions of temperature in a single crystal of V 3 Si in the unirradiated state and after neutron irradiation up to a fluence of 8.6 × 10 18 neutrons/cm 2 . In irradiated V 3 Si the temperature‐dependent distribution of electric field gradients at vanadium sites is observed. After the neutron irradiation the signs of tetragonal deformation appeared already at ≈ 35 K though only part of the irradiated sample exhibit the structural transformation. The Knight shift is found to be almost unaffected by the irradiation, in contrast to magnetic susceptibility and spin‐lattice relaxation time. The peculiarities of analysis of experimental data in homogeneous and inhomogeneous compounds are discussed.
