Summary

THE NMR DATA ON THE PHASE SEPARATION KINETICS OF HELIUM 3-HELIUM 4 SOLID SOLUTIONS AT 100 MILLIK ARE CONSIDERED. STUDIED ARE SOLID HELIUM SAMPLES WITH A HELIUM 3 CONTENT OF 0.54%. AN UNUSUALLY LONG PHASE SEPARATION TIME IS FOUND WHICH IS DEPENDENT ON THE PREHISTORY OF SAMPLE. THE SPIN DIFFUSION OF HELIUM 3 IN THE PHASE SEPARATED SOLUTION CONCENTRATED PHASE IS FOUND TO BE OF A QUASI-ONE-DIMENSIONAL NATURE WITH THE DIFFUSION COEFFICIENT VALUE TYPICAL OF LIQUID.
