Review Article


In recent years, extensive short-lived nuclear mass measurements have been carried out at the Heavy- Ion Research Facility (HIRFL) in Lanzhou using Isochronous Mass Spectrometry (IMS). The obtained mass values have been successfully applied to nuclear structure and astrophysics studies. In this contribution, we give a brief introduction to the nuclear mass measurements at HIRFL-CSR facility. Main technical developments are described and recent results are summarized. Furthermore, we envision the future perspective for the next-generation storage ring facility HIAF in Huizhou.

This review paper is fully dedicated to celebrating Professor Akito Arima’s 88th birthday. We express our sincere thanks to Prof. Akito Arima for promoting the collaboration between China and Japan in nuclear physics over the past decades, and particularly for his support on building the Cooler Storage Ring in Lanzhou, which is now a leading facility in the world for precision mass measurement of short-lived nuclei. This work was supported in part by the National Key R&D Program of China (Grant Nos. 2016YFA0400504 and 2018YFA0404400), the Key Research Program of Frontier Sciences of CAS (Grant No. QYZDJ-SSW-S), and the Helmholtz-CAS Joint Research Group HCJRG-108.
