Precision measurements in $^{\mathrm{\mathbf{20}}}$\textbf{F beta decay}

ORAL

Abstract

Precision measurements of the shape of the beta particle energy spectrum provide a sensitive window to search for new interactions beyond the standard model. The decay of $^{\mathrm{20}}$F offers an attractive system due to the simple decay scheme for a coincidence measurement. A beam of $^{\mathrm{20}}$F ions, produced at the National Superconducting Cyclotron Laboratory, was implanted into a beta-detector. A gamma-ray detection system surrounded the beta detector to detect the beta-delayed gammas in coincidence to reduce the background. Preliminary analysis of these data focus on the half-life of $^{\mathrm{20}}$F due to the statistical inconsistency of previous work. Monte Carlo simulations are ongoing to analyze the shape of the beta energy spectrum. Results of the analysis of the half-life will be presented.
