We report a measurement of the nuclear polarization of laser-cooled, optically-pumped \(^{37}\mathrm{K}\) atoms which will allow us to precisely measure angular correlation parameters in the beta-decay of the same atoms. These results will be used to test the \(V-A\) framework of the weak interactio...
