Simultaneous measurements of the β-neutrino angular correlation in ³²Ar pure Fermi and pure Gamow-Teller transitions using β-proton coincidences

RADIOACTIVITY ³²Ar(β⁺), (β⁺p)[from Ca(p, X), E=1.4 GeV]; measured Eβ⁺, Iβ⁺, Ep, Ip, pβ⁺-coin using plastic scintillator for β⁺ detection and silicon detectors for proton detection at ISOLDE-CERN facility; deduced β-neutrino angular correlation coefficients for Fermi and Gamow-Teller transitions. Comparison with theoretical predictions of Standard model. Relevance to constraints on exotic weak interactions, and future WISArD (weak-interaction studies with ³²Ar decay) research at CERN.
