The sedimentation of isotope atoms has been realized in monoatomic liquid and solid Se. It was observed that the concentration ratio 82Se/76Se increased by % level in the specimen ultracentrifuged at 0.7–0.9 million G under liquid and solid states. 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.
