Results from the Measurement of the $^{19}$Ne Half-Life at KVI

ORAL

Abstract

We report on the results of the 2009 measurement of the $^{19}$Ne half-life performed at the Trapped Radioactive Isotopes: Microlaboratories for Fundamental Physics (Tri$\mu$p) facility at the Kernfysisch Versneller Instituut (KVI). This system is a member of the set of T=$\frac{1}{2}$ mirror transitions, which can potentially be used to extract $V_{ud}$ with similar precision to the $0^+ \rightarrow 0^+$ decays. A blinded analysis of the data has yielded the half-life $17.2832 \pm 0.0077$ seconds, which is 1.2$\sigma$ from the global average used in a recent review of $\mathcal{F}$t values of the mirror transitions, and 6$\sigma$ from the average of the higher precision results performed at Princeton. We will review the systematic effects which contribute to the uncertainty, and discuss post-unblinding analysis efforts.
