“…Since this approach does not require cooling, short-lived ions (T 1/2 of order 10 µs) can be studied [473,471]. Future measurements at the ESR will probably also address the masses of neutron-rich nuclei, in particular those involved in the r process of stellar nucleosynthesis, as these can be produced efficiently by uranium projectile fission with subsequent separation in-flight by the FRS at GSI.…”

a b s t r a c tThe quest to comprehend how nuclear processes influence astrophysical phenomena is driving experimental and theoretical research programs worldwide. One of the main goals in nuclear astrophysics is to understand how energy is generated in stars, how elements are synthesized in stellar events and what the nature of neutron stars is. New experimental capabilities, the availability of radioactive beams and increased computational power paired with new astronomical observations have advanced the present knowledge. This review summarizes the progress in the field of nuclear astrophysics with a focus on the role of indirect methods and reactions involving beams of rare isotopes.

“…The maximum mass resolving power reaches m/δm = 180 000. Identification of the revolution time peaks is done by comparing the measured and a simulated spectra [22,32,33]. In order to determine the m/q ratios, nuclides with well-known masses [9] are used to calibrate the revolution time spectrum.…”

“…One way to achieve the latter is to use a special ion-optical setting of the ring and inject the ions with γ = γ t . This is the basis of the isochronous mass spectrometry (IMS) [21][22][23][24]. In the IMS, the velocity spreads of the ions are compensated by the orbit lengths and their revolution times are a direct measure of m/q of the ions.…”

Recent commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou enabled us to conduct high-precision mass measurements at the Institute of Modern Physics in Lanzhou (IMP). In the past few years, mass measurements were performed using the CSRe-based isochronous mass spectrometry employing the fragmentation of the energetic beams of 58 Ni, 78 Kr, 86 Kr, and 112 Sn projectiles. Masses of short-lived nuclides of on both sides of the stability valley were addressed. Relative mass precision of down to 10 −6 − 10 −7 is routinely achieved. The mass values were 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. In this contribution, we briefly review the so far conducted experiments and the main achieved results, as well as outline the plans for future experiments.

Abstract. Four campaigns of mass measurements for short-lived nuclei have been conducted using an isochronous mass spectrometry (IMS) technique at HIRFL-CSR (Cooler Storage Ring) in Lanzhou. The radioactive nuclei were produced by projectile fragmentation and injected into the experimental storage ring CSRe. Revolution times of the ions stored in the CSRe were measured from which masses of 78 Kr, 58 Ni, 86 Kr and 112 Sn fragments have been determined with a relative uncertainty of about 10 -6 -10 -7 . The experimental results are presented and their impacts on nucleosynthesis in the rp process and nuclear structure are discussed.
