Trapped-ion decay spectroscopy towards the determination of ground-state components of double-beta decay matrix elements
T. Brunner, A. Lapierre, C. Andreoiu +17
A new technique has been developed at TRIUMF's TITAN facility to perform in-trap decay spectroscopy. The aim of this technique is to eventually measure weak electron capture branch…
Extinction of the N=20 neutron-shell closure for 32Mg examined by direct mass measurements
A. Chaudhuri, C. Andreoiu, T. Brunner +12
The 'island of inversion' around Mg is one of the most important paradigm for studying the disappearance of the stabilizing 'magic' of a shell closure. We present the first…

Penning-trap mass spectrometry of highly charged, neutron-rich Rb and Sr isotopes in the vicinity of
V. V. Simon, T. Brunner, U. Chowdhury +12
The neutron-rich mass region around presents challenges for modeling the astrophysical -process because of rapid shape transitions. We report on mass measurements…
Elucidation of the anomalous A = 9 isospin quartet behaviour
M. Brodeur, T. Brunner, S. Ettenauer +5
Recent high-precision mass measurements of Li and Be, performed with the TITAN Penning trap at the TRIUMF ISAC facility, are analyzed in light of state-of-the-art shell…
New precision mass measurements of neutron-rich calcium and potassium isotopes and three-nucleon forces
A. T. Gallant, J. C. Bale, T. Brunner +18
We present precision Penning-trap mass measurements of neutron-rich calcium and potassium isotopes in the vicinity of neutron number N=32. Using the TITAN system the mass of $^{51}…
Highly charged ions in Penning traps, a new tool for resolving low lying isomeric states
A. T. Gallant, M. Brodeur, T. Brunner +11
The use of highly charged ions increases the precision and resolving power, in particular for short-lived species produced at on-line radio-isotope beam facilities, achievable with…
Penning-Trap Mass Measurements of the Neutron-Rich K and Ca Isotopes: Resurgence of the N = 28 Shell Strength
A. Lapierre, M. Brodeur, T. Brunner +9
We present Penning-trap mass measurements of neutron-rich 44,47-50K and 49,50Ca isotopes carried out at the TITAN facility at TRIUMF-ISAC. The 44K mass measurement was performed wi…
First experimental determination of the charge radius of Rb and its application in tests of the unitarity of the CKM matrix
E. Mané, A. Voss, J. A. Behr +9
Collinear-laser spectroscopy with bunched-beams technique was used for the study of neutron deficient Rb isotopes, out to Rb () at TRIUMF. The measured hyperfine cou…
First Use of High Charge States for Mass Measurements of Short-lived Nuclides in a Penning Trap
S. Ettenauer, M. C. Simon, A. T. Gallant +17
Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly-charged ions (HCI), using the TITAN facility at TRIUMF. Compared to singly…
A large Bradbury Nielsen ion gate with flexible wire spacing based on photo-etched stainless steel grids and its characterization applying symmetric and asymmetric potentials
T. Brunner, A. R. Mueller, K. O'Sullivan +9
Bradbury Nielsen gates are well known devices used to switch ion beams and are typically applied in mass or mobility spectrometers for separating beam constituents by their differe…
