The new mass values are up to 90 times more precise than previous measurements. While they suggest the persistence of the N=28 shell closure for argon, we show that this conclusion has to be nuanced in light of the wealth of spectroscopic data and theoretical investigations performed with the SDPF-U phenomenological shell model interaction. Our results are also compared with ab initio calculations using the valence space in-medium similarity renormalization group and the self-consistent Green's function approaches. Both calculations provide a very good account of mass systematics at and around Z=18 and, generally, a consistent description of the physics in this region.

\n The strength of the N=28 magic number in neutron-rich argon isotopes is examined through high-precision mass measurements of Ar46-48, performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. The new mass values are up to 90 times more precise than previous measurements. While they suggest the persistence of the N=28 shell closure for argon, we show that this conclusion has to be nuanced in light of the wealth of spectroscopic data and theoretical investigations performed with the SDPF-U phenomenological shell model interaction. Our results are also compared with ab initio calculations using the valence space in-medium similarity renormalization group and the self-consistent Green's function approaches. Both calculations provide a very good account of mass systematics at and around Z=18 and, generally, a consistent description of the physics in this region. This combined analysis indicates that Ar46 is the transition between the closed-shell Ca48 and collective S44.\n

A drift tube at the center of the MR-ToF MS allows decreasing or increasing the kinetic energy of the ion bunch, by switching its potential when the ions are traversing it. This offers the possibility of capturing and ejecting ion bunches by controlling a single voltage by the so-called in-trap lift technique. It also allows changing the energy of the trapped ions inside the MR-ToF MS, offering a way to optimize the resolving power of the device. For a fixed number of 2000 laps corresponding to a total ion flight time of about 30 ms, data was accumulated for 100 experimental cycles, adding to a duration of 10 s for each spectrum.

\n The mass resolving power of the multi-reflection time-of-flight mass spectrometer of ISOLTRAP was studied by monitoring 39K+ signals. A drift tube at the center of the MR-ToF MS allows decreasing or increasing the kinetic energy of the ion bunch, by switching its potential when the ions are traversing it. This offers the possibility of capturing and ejecting ion bunches by controlling a single voltage by the so-called in-trap lift technique. It also allows changing the energy of the trapped ions inside the MR-ToF MS, offering a way to optimize the resolving power of the device. For a fixed number of 2000 laps corresponding to a total ion flight time of about 30 ms, data was accumulated for 100 experimental cycles, adding to a duration of 10 s for each spectrum. Without any subsequent corrections for broadening effects, mass resolving powers in excess of 300 000 (FWHM) were obtained.\n

In particular, in ion-trapping devices, large amounts of contaminant ions result in significant systematic errors—if the measurements are possible at all. We present a solution for such cases: The ions from a quasi-continuous source are bunched in a linear radio-frequency-quadrupole ion trap, separated by a multi-reflection time-of-flight section followed by a Bradbury–Nielsen gate, and then captured in a Penning trap. Buffer-gas cooling is used to damp the ion motion in the latter, which allows a repeated opening of the Penning trap for a stacking of mass-selected ion bunches. Proof-of-principle demonstrations have been performed with the ISOLTRAP setup at ISOLDE/CERN, both with 133Cs+ ions from an off-line ion source and by application to an on-line beam of 179Lu+ ions contaminated with 163Dy16O+ ions.

\n The success of many measurements in analytical mass spectrometry as well as in precision mass determinations for atomic and nuclear physics is handicapped when the ion sources deliver “contaminations”, i.e., unwanted ions of masses similar to those of the ions of interest. In particular, in ion-trapping devices, large amounts of contaminant ions result in significant systematic errors—if the measurements are possible at all. We present a solution for such cases: The ions from a quasi-continuous source are bunched in a linear radio-frequency-quadrupole ion trap, separated by a multi-reflection time-of-flight section followed by a Bradbury–Nielsen gate, and then captured in a Penning trap. Buffer-gas cooling is used to damp the ion motion in the latter, which allows a repeated opening of the Penning trap for a stacking of mass-selected ion bunches. Proof-of-principle demonstrations have been performed with the ISOLTRAP setup at ISOLDE/CERN, both with 133Cs+ ions from an off-line ion source and by application to an on-line beam of 179Lu+ ions contaminated with 163Dy16O+ ions. In addition, an optimization of the experimental procedure is given, in particular for the number of ion bunches captured as a function of the ions’ lifetimes and the parameters of the experiment\n.\n

\n With the double Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN the masses of the neutron-rich isotopes Xe136-146 were measured with a relative uncertainty of the order of 10-8 to 10-7. In particular, the masses of Xe144-146 were measured for the first time. These new mass values allow one to extend calculations of the mass surface in this region.

The applicability of Penning trap mass spectrometry to mass measurements of exotic nuclei has been extended considerably at ISOLTRAP by improving and developing this double Penning trap mass spectrometer over the past two decades. The accurate determination of nuclear binding energies far from stability includes nuclei that are produced at rates less than 100 ions/s and with half-lives well below 100ms. The mass-resolving power reaches 107 corresponding to 10keV for medium heavy nuclei and the uncertainty of the resulting mass values has been pushed down to below 10-8. The article describes technical developments achieved since 1996 and the present performance of ISOLTRAP.\n

\n High-precision mass measurements of more than 30 neutron-rich nuclides around the Z=28 closed proton shell were performed with the triple-trap mass spectrometer ISOLTRAP at ISOLDE/CERN to address the question of a possible neutron shell closure at N=40. The results for Ni57,60,64-69 (Z=28), Cu65-74,76 (Z=29), and Ga63-65,68-78 (Z=31) have a relative uncertainty of the order of 10-8. In particular, the mass of Cu76 was measured for the first time. We analyze the resulting mass surface for signs of magicity, comparing the behavior of N=40 with that of known magic numbers and with midshell behavior. While the classic indications from the mass surface show no evidence for a shell closure at N=40, there is evidence for a weak-and very localized-effect for Z=28, consistent with findings from nuclear spectroscopy studies. © 2007 The American Physical Society.\n

\n The triple-trap mass spectrometer ISOLTRAP at ISOLDE/CERN has demonstrated the feasibility of mass spectrometry of in-trap-decay product ions. This novel technique gives access to radionuclides, which are not produced directly at ISOL-type radioactive ion beam facilities. As a proof of principle, the in-trap decay of 37K + has been investigated in a Penning trap filled with helium buffer gas. The half-life of the mother nuclide was confirmed and the recoiling 37Ar + daughter ion was contained within the trap. The ions of either the mother or the daughter nuclide were transferred to a precision Penning trap, where their mass was determined. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.\n
