It was observed that the concentration ratio $^{82}$ Se/ $^{76}$ Se increased by % level in the specimen ultracentrifuged at 0.70.9 million G and at 300 $^{circ}$ C(liquid state) or 190 $^{circ}$ C (solid state), respectively. The present result is evidence of sedimentation of substitutional atoms in condensed matter via self-diffusion, and suggests its possible application to isotope separation by condensed matter centrifugation.
