TITAN mass measurements of neutron-rich Cs, Ba and r-process lanthanide abundances

T. -H. Yeh, J. D. Cardona, Y. Wang +26

We present measurements for the masses of five neutron-rich isotopes, Cs and Ba, probed for the first time by TITAN at TRIUMF with time-of-flight measureme…

First direct measurement of Ca single -decay Q value with the TITAN Penning trap

S. Kakkar, D. Perera, J. Ash +19

Neutrinoless double -decay (0), if observed, would provide unequivocal evidence of physics beyond the Standard Model. Ca is an interesting candidate system to study…

Mass measurements of Yb identify an anomalous proton-neutron interaction

C. L. Brown, J. Ash, B. Ashrafkhani +30

Mass measurements of nuclei can identify structurally-driven trends in binding energy across isotopic chains, and can also isolate specific nucleon-nucleon interactions, such as th…

Refined topology of the N = 20 island of inversion with high precision mass measurements of Na and Mg

E. M. Lykiardopoulou, C. Walls, J. Bergmann +30

Mass measurements of Na and Mg using the TITAN MR-TOF-MS at TRIUMF's ISAC facility are presented, with the uncertainty of the Na mass reduced by over two…

Precision mass measurements of Sr using TITAN's Multiple-Reflection Time-of-Flight Mass Spectrometer

Z. Hockenbery, T. Murböck, B. Ashrafkhani +29

We report precision mass measurements of Sr performed with the TITAN Multiple-Reflection Time-of-Flight Mass Spectrometer. This marks a first time mass measurement of $^{…

Convergence on the Proton Drip-Line in Thulium

B. Kootte, M. P. Reiter, C. Andreoiu +35

Direct observation of proton emission for very small Q-values is often unfeasible due to the long partial half-lives of the proton emission channel associated with tunneling throug…

High-precision mass measurement of Sn restores smoothness of the mass surface

C. M. Ireland, F. M. Maier, G. Bollen +20

As a step towards the ultimate goal of a high-precision mass measurement of doubly-magic Sn, the mass of Sn was measured at the Low Energy Beam and Ion Trap (LEBIT)…

Direct mass measurements of neutron-rich zinc and gallium isotopes: an investigation of the formation of the first r-process peak

Andrew Jacobs, Stylianos Nikas, John Ash +23

The prediction of isotopic abundances resulting from the rapid neutron capture process (r-process) requires high-precision mass measurements. Using TITAN's on-line time-of-flight s…

Collision-Induced Dissociation at TRIUMF's Ion Trap for Atomic and Nuclear science

A. Jacobs, C. Andreoiu, J. Bergmann +26

The performance of high-precision mass spectrometry of radioactive isotopes can often be hindered by large amounts of contamination, including molecular species, stemming from the…

Mapping the Island of Inversion: Precision Mass Measurements of Neutron-rich Fe Isotopes

W. S. Porter, B. Ashrafkhani, J. Bergmann +32

Nuclear properties across the chart of nuclides are key to improving and validating our understanding of the strong interaction in nuclear physics. We present high-precision mass m…

Mass measurements of Ga reduce x-ray burst model uncertainties and extend the evaluated isobaric multiplet mass equation

S. F. Paul, J. Bergmann, J. D. Cardona +27

We report precision mass measurements of neutron-deficient gallium isotopes approaching the proton drip line. The measurements of Ga performed with the TITAN multiple-ref…

Improving nonstoquastic quantum annealing with spin-reversal transformations

Eleni Marina Lykiardopoulou, Alex Zucca, Sam A. Scivier +1

Nonstoquastic Hamiltonians are hard to simulate due to the sign problem in quantum Monte Carlo simulation. It is however unclear whether nonstoquasticity can lead to advantage in q…
