Ft value for the superallowed decay of $^{32}$Ar

ORAL

Abstract

$^{32}$Ar produced by fragmentation at the NSCL at MSU was implanted into a Si detector. Beta-delayed protons and gammas were measured with the help of additional Si detectors and Ge detectors. We were able to determine the superallowed branch with a precision of $\approx 0.5$\%. With this information plus the half-life and endpoint from previous work we extract the $f t$ value which allows for a comparison of predicted versus measured isospin-breaking correction. Results will be presented.
