Precise branching ratio measurements in ¹⁹Ne β decay and fundamental tests of the weak interaction

RADIOACTIVITY ¹⁹Ne(β⁺)[from C, Si(p, X), E=500 MeV at TRIUMF facility]; measured Eγ, Iγ, electron spectra, βγ-coin using the 8π γ-ray spectrometer and SCEPTAR detector array at TRIUMF-ISAC facility. ¹⁹F; deduced levels, β⁺-branching ratios, precise β branch for superallowed ground-state to ground-state branch, Ft values, V_ud element of the CKM quark-mixing matrix. Comparison with previous experimental results. Discussed implications for testing weak interaction symmetries.
