“…[31], but it improves the uncertainty by more than two orders of magnitude as compared with the AME1995. A measurement also made at ISOLDE in 2000 with the transmission mass spectrometer MISTRAL (2006Lu.1 [58]) yielded a mass excess of −51 940(120) keV, confirming our mass using a different measurement principle. Because of the much higher precision of our datum, the other two experimental results are outweighed, while the prediction of Ref.…”

The atomic masses of the neutron-deficient radioactive rubidium isotopes [74][75][76][77]79,80,83 Rb have been measured with the Penning trap mass spectrometer ISOLTRAP. Using the time-of-flight cyclotron resonance technique, relative mass uncertainties ranging from 1.6 × 10 −8 to 5.6 × 10 −8 were achieved. In all cases, the mass precision was significantly improved as compared with the prior Atomic-Mass Evaluation; no significant deviations from the literature values were observed. The exotic nuclide 74 Rb, with a half-life of only 65 ms, is the shortest-lived nuclide on which a high-precision mass measurement in a Penning trap has been carried out. The significance of these measurements for a check of the conserved-vector-current hypothesis of the weak interaction and the unitarity of the Cabibbo-Kobayashi-Maskawa matrix is discussed.

“…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. Another frequency-based mass measurement concept is implemented at ISOLDE with the radiofrequency transmission mass spectrometer MISTRAL [474,475], where in a homogeneous magnetic field a controlled and coherent manipulation of the ion trajectory is performed to determine the mass via the cyclotron frequency.…”

Nuclear astrophysics with radioactive beams

2010

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 local corrections are derived either from a linear fit (as above), if the doublets differ in mass number, or by using the offset of the A 10 ( 10 B-10 Be) doublet to correct the A 11 ( 11 B-11 Li) doublet (this procedure was confirmed by using 76 Ge-76 Rb to calibrate 74 Ge-74 Rb in Ref. [19]). The average corrected value for 11 Li is ÿ74:0 5:2 10 ÿ7 , consistent with the global approach.…”
