The role of β decay as a low-energy probe of physics beyond the standard model is
reviewed. Traditional searches for deviations from the standard model structure of the weak …

Since 1999, the TRIUMF-ISAC facility has been providing rare isotope beams for nuclear
physics experiments. The three pillars of the program are nuclear structure, nuclear …

The precision of correlation measurements in neutron and nuclear β decay has now
reached the level of about 1% and better. At this level of precision, higher-order corrections …

The beta decay process offers unique possibilities to search for so-called exotic, non-
standard model components in the weak interaction, and for testing its fundamental …

Background: Theoretical approaches based on energy density functionals (EDF) are gaining
in popularity due to their broad range of applicability. One of their key features is the proper …

Background: The precise determination of the F t value in T= 1/2 mixed mirror decays is an
important avenue for testing the standard model of the electroweak interaction through the …

The experimental achievements and the current program with the LPCTrap device installed
at the LIRAT beam line of the SPIRAL1‐GANIL facility are presented. The device is …

The 1 2+→ 1 2+ superallowed mixed mirror decay of Ne 19 to F 19 is excellently suited for
high precision studies of the weak interaction. However, there is some disagreement on the …

The half-life of K 37 has been measured to be 1.23651 (94) s, a value nearly an order of
magnitude more precise than the best previously reported. The β+ decay of K 37 occurs …

We report the first direct measurement of the transition energy Q EC of the Na 21 mixed
Fermi–Gamow-Teller decay. This is the first of the T= 1/2 mirror nuclei decays used for the …
