Measurement of the $\gamma$ branches in the $\beta^+$ decay of $^{\mathrm 32}$Cl

As discussed in the previous talk (A.~Garc\'ia, et al.), one of the dominant systematic uncertainties in the measurement of the $ft$ value of $^{\mathrm 32}$Ar arises from the uncertainty in the HPGe $\gamma$ efficiency. The $\gamma$s emitted in the decay of $^{\mathrm 32}$Cl cover the same range of energies and, since $\approx10\%$ of the time it is a daughter product of $^{\mathrm 32}$Ar, a precise knowledge of these branches will provide us with an \emph{in situ} calibration of our HPGe detectors. This talk will describe the experiment and results of the measurement performed at the Texas A \& M Cylcotron Institute. We have identified a number of new branches and determined the $\gamma$ yields to $<0.3\%$, generally an order of magnitude improvement from previous results. Implications for the $^{\mathrm 32}$Ar experiment will be discussed.
