Direct determination of the atomic mass difference of Re187 and Os187 for neutrino physics and cosmochronology
D. A. Nesterenko, S. Eliseev, K. Blaum +10
For the first time a direct determination of the atomic mass difference of 187Re and 187Os has been performed with the Penning-trap mass spectrometer SHIPTRAP applying the novel ph…
Mass measurements of neutron-rich Rb and Sr isotopes
R. Klawitter, A. Bader, M. Brodeur +16
We report on the mass measurements of several neutron-rich and isotopes in the region with the TITAN Penning-trap mass spectrometer. Usi…
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…
New determination of double-beta-decay properties in 48Ca: high-precision Q-value measurement and improved nuclear matrix element calculations
A. A. Kwiatkowski, T. Brunner, J. D. Holt +16
We report a direct measurement of the Q-value of the neutrinoless double-beta-decay candidate 48Ca at the TITAN Penning-trap mass spectrometer, with the result that Q = 4267.98(32)…
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…
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…
Verifying the accuracy of the TITAN Penning-trap mass spectrometer

TITAN (TRIUMF's Ion Traps for Atomic and Nuclear science) is an online facility designed to carry out high-precision mass measurements on singly and highly charged radioactive ions…
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 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…
