We have been studying a stable isotope separation/enrichment using Ion-Cyclotron-Resonance (ICR) method. Since most of basic technologies for the ICR method has been accumulated and exits in the accelerator science, we could start the study using equipment available in KEK. Here, we report the status of the study. While a slight effect of enrichment for zinc isotopes has been observed, many problems still remain. We are looking forward to receiving helpful suggestions.
