A first extraction of the weak magnetism form factor and Fierz interference term from the In Sn Gamow-Teller transition
L. De Keukeleere, D. Rozpedzik, N. Severijns +5
Spectrum shape measurements in nuclear decay can be used to test physics beyond the Standard Model with results being complementary to high-energy collider experiments. In part…

Simultaneous Measurements of the Beta Neutrino Angular Correlation in Ar Pure Fermi and Pure Gamow-Teller Transitions using Beta-Proton Coincidences
V. Araujo-Escalona, D. Atanasov, X. Fléchard +14
We report first time measurements of the beta-neutrino angular correlation based on the kinetic energy shift of protons emitted in parallel or anti-parallel directions with respect…
