A strong gravitational field resulted in the sedimentation of isotope atoms in monatomic liquid. The concentration ratio $$^{82}$$Se/$$^{76}$$Se increased by greater than 3.5% in specimen ultracentrifuged at 0.7$$sim$$0.9 million G and at 300$$^{circ}$$C. The recovered sample had a feather-shaped crystalline morphology. The concentration gradient was nearly twice that of the steady state analytical result (ideal gas system), indicating a non-ideal system diffusion. The present result is evidence of sedimentation of substitutional atoms in condensed matter via self-diffusion, and suggestes its possible application to isotope separation, crystalline control and matter dynamics in massive star.
