A resonance in the ${\mathrm{Li}}^{7}$+$d$ reaction at a deuteron bombarding energy of 361\ifmmode\pm\else\textpm\fi{}2 keV, corresponding to a level in ${\mathrm{Be}}^{9}$ at 16.97 MeV, has been investigated. Total cross sections for ${\mathrm{Li}}^{7}(d, {p}_{0}){\mathrm{Li}}^{8}$ were measured by detecting induced ${\mathrm{Li}}^{8}$ activity for deuteron energies between 340 and 780 keV. In agreement with earlier work of Woods and Wilkinson, a resonance in this reaction was observed on a background rapidly decreasing with decreasing deuteron energy. This resonance and the surrounding region from 0.1 to 1.1 MeV were also studied with the ${\mathrm{Li}}^{7}(d, \ensuremath{\gamma}){\mathrm{Be}}^{9}$ reaction by measuring the yield of the gamma-ray transitions to the lower states of ${\mathrm{Be}}^{9}$ with a NaI crystal. The measured width of the level was less than 600 eV in the laboratory system. The angular distribution of the on-resonance gamma rays to the ground state was isotropic to within 7%. Branching ratios for the gamma rays to several states in ${\mathrm{Be}}^{9}$ were measured with a NaI crystal, a scintillation pair spectrometer, and a NaI crystal surrounded by an anticoincidence shield. The relative intensities for the gamma-ray transitions to the ground state and to the states at 1.70, 2.43, 3.04, and 4.74 MeV were found to be 100, 8.5\ifmmode\pm\else\textpm\fi{}4.3, 10.6\ifmmode\pm\else\textpm\fi{}5.3, \ensuremath{\le}4.5, and 9.6\ifmmode\pm\else\textpm\fi{}4.8, respectively. The 15.3-MeV gamma-ray transition indicates the existence of a level in the usual sense at 1.70 MeV in ${\mathrm{Be}}^{9}$. From the gamma-ray measurements below resonance at 300 keV an upper limit of 1.6\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}30}$ ${\mathrm{cm}}^{2}$ was found for the direct ($d, \ensuremath{\gamma}$) cross section to low-energy states in ${\mathrm{Be}}^{9}$. For the ${\mathrm{Li}}^{7}(d, n)$ reaction, the yield of neutrons with energies above 10 MeV showed a resonance at the same energy. From neutron time-of-flight measurements relative to coincident gamma rays, neutron groups were seen corresponding to breakup of levels in ${\mathrm{Be}}^{9}$ at 2.43 and 4.74 MeV. The ${\mathrm{Li}}^{7}(d, d){\mathrm{Li}}^{7}$ and ${\mathrm{Li}}^{7}(\mathrm{d}, \ensuremath{\alpha}){\mathrm{He}}^{5}$ reactions did not show observable resonance effects. From the above results, the reduced widths for neutron and alpha-particle emission are found to be considerably smaller than the corresponding width for protons, thus supporting the hypothesis that the state in ${\mathrm{Be}}^{9}$ at 16.97 MeV has an isobaric spin of $\frac{3}{2}$.
