文摘

With the successful commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou accurate mass measurements of short-lived nuclides became possible by employing isochronous mass spectrometry. A series of experiments have been carried out in the past few years using projectile fragmentation of ⁷⁸Kr, ⁸⁶Kr, ⁵⁸Ni, and ¹¹²Sn beams. Masses of 16 nuclides have been obtained for the first time. The mass data have been used as an input for dedicated nuclear structure and astrophysics studies, providing for instance new insights into the rp-process of nucleosynthesis in X-ray bursts. Here we review the so far conducted experiments and the main results, as well as outline the plans for future experiments.
