Precise half-life determination of the mixed-mirror β-decaying ¹⁵O

RADIOACTIVITY ¹⁵O(β⁺)[from ²H(¹⁴N, n), E=39 MeV]; measured Eβ, Iβ, T_1/2 of ¹⁵O decay using a plastic scintillator at the β-Counting Station of the Nuclear Science Laboratory of University Notre Dame. Comparison with previous experimental results. Relevance to future determinations of Cabibbo-Kobayashi-Maskawa (CKM) matrix V_ud for superallowed mirror transitions of 1/2 isospin.

NUCLEAR REACTIONS ²H(¹⁴N, n)¹H/⁴He/⁶Li/¹²C/¹³C/¹⁴N/¹⁵N/¹⁵O, E=39 MeV; measured reaction products, particle identification plot.
