“…Therefore, either because of yield or because of accuracy, the mass measurements addressed in this publication must be carried out using one ion at a time in the trap. There are worldwide two Penning trap mass spectrometers in operation which are designed to measure the mass of a single stable isotope with ultimate accuracy: the one developed at the University of Washington (UW-PTMS) by Van Dyck et al [25], now at the Max-Planck Institute for Nuclear Physics in Heidelberg in the division of Blaum [26], and the one developed at MIT by Pritchard et al [27] which was relocated in 2004 at FSU in Florida and is now operated with on-going success by the group of Myers [28].…”

A novel device, called quantum sensor, has been conceived to measure the mass of a single ion with ultimate accuracy and unprecedented sensitivity while the ion is stored and cooled in a trap. The quantum sensor consists of a single calcium ion as sensor, which is laser cooled to mK temperatures and stored in a second trap connected to the trap for the ion under study by a common endcap. The cyclotron motion of the ion under investigation is transformed into axial motion along the magnetic field lines and coupled to the sensor ion by the image current induced in the common endcap. The axial motion of the sensor ion in turn is monitored spatially resolved by its fluorescence light. In this way the detection of phonons can be upgraded to a detection of photons. This device will allow one to overcome recent limitations in high-precision mass spectrometry.

“…Moreover, the last decades have witnessed a significant progress in developing optical laser spectroscopy techniques that allow probing of the structure of stable and especially radioactive nuclei. Combined with modern accelerator and storage ring facilities, these techniques allow very accurate investigations of short-living exotic isotopes which are available only in small quantities [3][4][5][6][7].…”

Hyperfine-induced effects on the linear polarization ofKα1emission from heliumlike ions

et al. 2013

The linear polarization of the characteristic photon emission from few-electron ions is studied for its sensitivity with regard to the nuclear spin and magnetic moment of the ions. Special attention is paid, in particular, to the Kα1 (1s2p 3/2 1,3 P1,2 → 1s 2 1 S0) decay of selected helium-like ions following the radiative electron capture into initially hydrogen-like species. Based on the density matrix theory, a unified description is developed that includes both, the many-electron and hyperfine interactions as well as the multipole-mixing effects arising from the expansion of the radiation field. It is shown that the polarization of the Kα1 line can be significantly affected by the mutipole mixing between the leading M 2 and hyperfine-induced E1 components of 1s2p 3 P2, Fi → 1s 2 1 S0, F f transitions. This E1-M 2 mixing strongly depends on the nuclear properties of the considered isotopes and can be addressed experimentally at existing heavy-ion storage rings.

“…6(a). In the last decade, Penning trap facilities have contributed not only by obtaining precise mass values for nuclides near the stability line, but, together with the storage ring facilities (to be discussed below), providing valuable experimental results for a wealth of unstable, short-lived nuclides [31]. …”

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

et al. 2015

View full text Add to dashboard Cite

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.
