The level structure of ${}_{}{}^{200}{}_{}{}^{}\mathrm{Hg}$ has been studied by the ($\mathrm{n},{\mathrm{n}}^{\prime }\gamma$) reaction. All previously identified levels below 2 MeV are confirmed, and some aspects of the low-lying structure have been clarified.

[NUCLEAR REACTIONS ${}_{}{}^{200}{}_{}{}^{}\mathrm{Hg}(\mathrm{n},{\mathrm{n}}^{\prime }\gamma )$, $E_n=1.0-3.5\mathrm{}$ MeV; measured $E_{\gamma }$, $I_{\gamma }$, $\sigma (E,E_{\gamma },{125}^{\circ })$, $\sigma (E_{\gamma },{\theta }_{\gamma })$. Deduced levels, $J$, $\pi$. Enriched target.]
