Abstract	Phase structure of rapidly quenched solid helium samples is studied by the NMR technique on dilute $^{3}$He–$^{4}$He mixtures. The pulse NMR method is used for measurements of spin–spin T $_{2}$ relaxation time and spin diffusion coefficient D for all coexisting phases. It was found that quenched samples are two-phase systems consisting of the hcp matrix and some inclusions which are characterized by D and T $_{2}$ values close to those in liquid phase. Such liquid-like inclusions undergo a spontaneous transition to a new state with anomalously short T $_{2}$ times. It is found that inclusions observed in both the states disappear on careful annealing near the melting curve. It is assumed that the liquid-like inclusions transform into a new state—a glass or a crystal with a large number of dislocations. These disordered inclusions may be responsible for the anomalous phenomena observed in supersolid region.
