Precise branching ratio measurements in Ne beta decay and fundamental tests of the weak interaction
B. M. Rebeiro, S. Triambak, P. Z. Mabika +25
We used the 8 -ray spectrometer at the TRIUMF-ISAC radiocative ion beam facility to obtain high-precision branching ratios for Ne $β^+$ decay to excited states in $…
Precision measurements with LPCTrap at GANIL
E. Lienard, G. Ban, C. Couratin +15
The experimental achievements and the results obtained so far with the LPCTrap device installed at GANIL are presented. The apparatus is dedicated to the study of the weak interact…
Branching ratio of the super-allowed beta decay of 10C
B. Blank, M. Aouadi, P. Ascher +9
In an experiment performed at the ISOLDE facility of CERN, the super-allowed beta-decay branching ratio of 10C was determined with a high-precision single-crystal germanium detecto…
Measurement of the -asymmetry parameter of Cu in search for tensor type currents in the weak interaction
G. Soti, F. Wauters, M. Breitenfeldt +11
Precision measurements at low energy search for physics beyond the Standard Model in a way complementary to searches for new particles at colliders. In the weak sector the most gen…
Electron shakeoff following the \b{eta}+ decay of 19Ne+ and 35Ar+ trapped ions
X. Fabian, X. Fléchard, B. Pons +16
The electron shakeoff of 19F and 35Cl atoms resulting from the \b{eta}+ decay of 19Ne+ and 35Ar+ ions has been investigated using a Paul trap coupled to a time of flight recoil-ion…
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…
High-Precision Branching Ratio Measurement and Spin Assignment Implications for Ga Superallowed Decay
A. D. MacLean, A. T. Laffoley, C. E. Svensson +48
A high-precision branching ratio measurement for the superallowed Fermi $β^{+}$ emitter Ga was performed with the Gamma-Ray Infrastructure for Fundamental Investigations of…
High-Precision Measurement of the 19Ne Half-Life and Implications for Right-Handed Weak Currents
S. Triambak, P. Finlay, C. S. Sumithrarachchi +21
We report a precise determination of the 19Ne half-life to be s. This result disagrees with the most recent precision measurements and is important for…
Performance of Geant4 in simulating semiconductor particle detector response in the energy range below 1 MeV
G. Soti, F. Wauters, M. Breitenfeldt +6
Geant4 simulations play a crucial role in the analysis and interpretation of experiments providing low energy precision tests of the Standard Model. This paper focuses on the accur…
