Calculation of parity mixing inF19

The conventional model of weak interactions is tested in the case of the recently measured $\gamma$ asymmetry in ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$. It is shown that the conventional model leads to an asymmetry $\delta$ about one-fourth to one-third of the experimental value. Extra currents in the hadronic part of the weak interaction could be an explanation for this discrepancy.
