Using thermal diffusion of CO, we obtained an enrichment factor of about 3 for ^\u003c13\u003eC for half-gram carbon in 5 days. This means we expect for ^\u003c14\u003eC an enrichment factor of 9,corresponding to an extension of the radiocarbon time scale by \u003e20,000 years. With small modification of this system, it would be possible to perform higher isotope enrichment of ^\u003c14\u003eC.
