“…However, our value deviates by 1.5 standard deviations from the result M E = −79384(28) keV of an ESR Schottky measurement [82], which is not used in the adjustment procedure of the Atomic Mass Evaluation due to its higher uncertainty. 89 Mo: The value from JYFLTRAP agrees with the AME2003 value, which is determined via a reaction Q-value measurement 92 Mo( 3 He, 6 He) 89 Mo from a study at MSU [83] and the mass of the primary nuclide 92 Mo.…”

“…However, considering the prevalent discrepancies among the available literature this nuclide should be addressed in a future measurement. (6,7,8) were observed in coincidence with γ rays. The β-decay endpoint energies were measured by β-γ coincidence gated on the 741-keV γ ray and the derived Q EC values of 88 Tc were given in two different papers [70,71].…”

The masses of very neutron-deficient nuclides close to the astrophysical rp-and νp-process paths have been determined with the Penning trap facilities JYFLTRAP at JYFL/Jyväskylä and SHIP-TRAP at GSI/Darmstadt. Isotopes from yttrium (Z = 39) to palladium (Z = 46) have been produced in heavy-ion fusion-evaporation reactions. In total 21 nuclides were studied and almost half of the mass values were experimentally determined for the first time:88 Tc,

“…Within a year, a second Penning-trap measurement [61] had confirmed the new 46 V result and had also found that the 42 Sc Q EC value differed from the Vonach result by six times the latter's quoted uncertainty. Two years later, another Penning-trap measurement [62] indicated that the 50 Mn and 54 Co Q EC values also differed from Vonach's results by a similar amount. These most-recent Penning-trap results quoted 0.1-keV uncertainties.…”

The open squares are the results of Penning-trap measurements [61,62,73,149]; the filled squares are from combined (p, γ ) and (n, γ ) measurements (see Ref.

A new critical survey is presented of all half-life, decay-energy, and branching-ratio measurements related to 20 superallowed 0 + → 0 + β decays. Compared with our last review, there are numerous improvements: First, we have added 27 recently published measurements and eliminated 9 references, either because they have been superseded by much more precise modern results or because there are now reasons to consider them fatally flawed; of particular importance, the new data include a number of high-precision Penning-trap measurements of decay energies. Second, we have used the recently improved isospin symmetry-breaking corrections, which were motivated by these new Penning-trap results. Third, our calculation of the statistical rate function f now accounts for possible excitation in the daughter atom, a small effect but one that merits inclusion at the present level of experimental precision. Finally, we have re-examined the systematic uncertainty associated with the isospin symmetry-breaking corrections by evaluating the radial-overlap correction using Hartree-Fock radial wave functions and comparing the results with our earlier calculations, which used Saxon-Woods wave functions; the provision for systematic uncertainty has been changed as a consequence. The new "corrected" Ft values are impressively constant and their average, when combined with the muon lifetime, yields the up-down quark-mixing element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, V ud = 0.97425 ± 0.00022. The unitarity test on the top row of the matrix becomes |V ud | 2 + |V us | 2 + |V ub | 2 = 0.99995 ± 0.00061. Both V ud and the unitarity sum have significantly reduced uncertainties compared with our previous survey, although the new value of V ud is statistically consistent with the old one. From these data we also set limits on the possible existence of scalar interactions, right-hand currents, and extra Z bosons. Finally, we discuss the priorities for future theoretical and experimental work with the goal of making the CKM unitarity test even more definitive.

“…The necessary relative uncertainty of the mass measurement depends on the physics being investigated and ranges from δm/m ≈ 10 −7 − 10 −8 in the field of nuclear physics [4,5,6] and astrophysics [7,8,9,10], down to the smallest possible uncertainties of better than 10 −11 for tests of fundamental interactions and their symmetries [11,12,13,14,15,16,17,18,19,20,21,22,23]. Penning traps are nowadays the most suitable devices for high-precision mass measurements of nuclides.…”

PENTATRAP: a novel cryogenic multi-Penning-trap experiment for high-precision mass measurements on highly charged ions

et al. 2012

View full text Add to dashboard Cite

The novel five-Penning trap mass spectrometer Pentatrap is developed at the Max-Planck-Institut für Kernphysik (MPIK), Heidelberg. Ions of interest are long-lived highly charged nuclides up to bare uranium. Pentatrap aims for an accuracy of a few parts in 10 12 for mass ratios of mass doublets. A physics program for Pentatrap includes Q-values measurements of β-transitions relevant for neutrino physics, stringent tests of quantum electrodynamics in the regime of extreme electric fields, and a test of special relativity. Main features of Pentatrap are an access to a source of highly charged ions, a multi-trap configuration, simultaneous measurements of frequencies, a continuous precise monitoring of magnetic field fluctuations, a fast exchange between different ions, and a highly sensitive cryogenic non-destructive detection system. This paper gives a motivation for the new mass spectrometer Pentatrap, presents its experimental setup, and describes the present status.
