Weak Interaction and Parity Nonconservation in the Photodisintegration and Electrodisintegration of the Deuteron near Threshold

I calculate the asymmetries in the integrated cross sections for ${}_{}{}^2{}_{}{}^{}\mathrm{H}({\gamma }_{\mathrm{pol}}, n)p$ and ${}_{}{}^2{}_{}{}^{}\mathrm{H}(e_{\mathrm{pol}}, n)e^{\prime }p$, with left- and right-polarized incident particles. Up to 1 MeV above threshold, the rising $p$-wave amplitude in the final $\mathrm{np}$ system is shown to have not destroyed the close relation between the asymmetries and the circular polarization of the photon in $p(n_0, {\gamma }_{\mathrm{pol}}){}_{}{}^2{}_{}{}^{}\mathrm{H}$.
