Energy levels of ${}_{}{}^{239}{}_{}{}^{}\mathrm{U}$ up to an excitation energy of 1.6 MeV have been studied with the ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}\mathrm{}(d,p)\mathrm{}{}_{}{}^{239}{}_{}{}^{}\mathrm{U}$ reaction at a bombarding energy of 12 MeV. Angular distributions $75°\le {\theta }_L<150\mathrm{}°$ provided information on the $l$ values transferred. Level assignments based on the ($d,p$)-data are suggested which partially corroborate recent studies of ${}_{}{}^{239}{}_{}{}^{}\mathrm{U}$ with neutron-capture $\gamma$ rays.

NUCLEAR REACTIONS ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}\mathrm{}(d,p)\mathrm{}$, $E=12\mathrm{}$ MeV; measured $E_x$ and $\sigma \left(\theta \right)$; ${}_{}{}^{239}{}_{}{}^{}\mathrm{U}$ deduced levels, $l$, $J$, $\pi$, Nilsson assignments.
