“…The physics program at the rings is rich and goes beyond investigations of nuclear ground-state properties, see, e.g., 05003-p.3 [159,160,161,162,163,164,165,166]. Decays of highly-charged ions will be studied within the ILIMA experiments [167,168].…”

Abstract. Access to stored and cooled highly-charged radionuclides offers unprecedented opportunities to perform high-precision investigations of their decays. Since the few-electron ions, e.g. hydrogen-or helium-like ions, are quantum mechanical systems with clear electronic ground state configurations, the decay studies of such ions are performed under well-defined conditions and allow for addressing fundamental aspects of the decay process. Presented here is a compact review of the relevant experiments conducted at the Experimental Storage Ring ESR of GSI. A particular emphasis is given to the investigations of the two-body beta decay, namely the bound-state β-decay and its time-mirrored counterpart, orbital electron-capture.

“…Ions with energies between 0.1 AMeV and 10 AMeV can be efficiently stored in ion storage rings [10,11]. The combination of such a ring with a reactor could open the path to direct measurements of neutron-induced cross sections on short-lived radioactive isotopes in the keV-regime [12].…”

Abstract. The huge neutron fluxes offer the possibility to use research reactors to produce isotopes of interest, which can be investigated afterwards. An example is the half-lives of long-lived isotopes like 129 I. A direct usage of reactor neutrons in the astrophysical energy regime is only possible, if the corresponding ions are not at rest in the laboratory frame. The combination of an ion storage ring with a reactor and a neutron guide could open the path to direct measurements of neutron-induced cross sections on short-lived radioactive isotopes in the astrophysically interesting energy regime.

“…4 and 6, is owed largely to these two methods. Penning trap mass measurement facilities [9,29] exist in many nuclear physics laboratories, whereas presently there are only two heavy-ion storage ring facilities performing mass measurements of exotic nuclei [30], experimental storage ring (ESR) at GSI (Germany) and CSRe at IMP/CAS at Lanzhou. In this section, we will give a short overview of various methods and their characteristics, with a focus on their advantages and limitations, as well as possible ways to improve them toward measurements of r-process nuclei.…”

Toward precision mass measurements of neutron-rich nuclei relevant to r-process nucleosynthesis

et al. 2015

The open question of where, when, and how the heavy elements beyond iron enrich our Universe has triggered a new era in nuclear physics studies. Of all the relevant nuclear physics inputs, the mass of very neutron-rich nuclides is a key quantity for revealing the origin of heavy elements beyond iron. Although the precise determination of this property is a great challenge, enormous progress has been made in recent decades, and it has contributed significantly to both nuclear structure and astrophysical nucleosynthesis studies. In this review, we first survey our present knowledge of the nuclear mass surface, emphasizing the importance of nuclear mass precision in r-process calculations. We then discuss recent progress in various methods of nuclear mass measurement with a few selected examples. For each method, we focus on recent breakthroughs and discuss possible ways of improving the weighing of r-process nuclides.
