摘要：
A novel method for mass measurements of short-lived exotic nuclides is presented. Exotic nuclides were produced and separated in flight at relativistic energies: with the fragment separator (FRS) and were injected into the experimental storage ring (ESR). Operating the ESR in the isochronous mode we performed mass measurements of neutron deficient fragments of Kr-84 with half-lives larger than 50 ms. However, this experimental technique is applicable in a half-life range down to a few mus. A mass resolving power of 110000 (FWHM) has been achieved. Results are presented for the masses of As-68, Se-70,Se-71 and Br-73.
