Ternary fission of $^{252}\mathrm{Cf}$ was studied at Gammasphere with eight $\ensuremath{\Delta}E\ifmmode\times\else\texttimes\fi{}E$ particle telescopes. After Doppler correction, the $3368\phantom{\rule{0.3em}{0ex}}\text{keV}\phantom{\rule{0.3em}{0ex}}{2}^{+}\ensuremath{\rightarrow}{0}^{+}$ transition in $^{10}\mathrm{Be}$ was found in coincidence with the $^{10}\mathrm{Be}$ fragments with no evidence for any $\ensuremath{\gamma}$ rays not Doppler shifted for $^{10}\mathrm{Be}$ with $>21\phantom{\rule{0.3em}{0ex}}\text{MeV}$ kinetic energy. The ratio of the first ${2}^{+}$ to ground-state population probabilities was estimated as $N({2}^{+})∕N({0}^{+})=0.160\ifmmode\pm\else\textpm\fi{}0.025$. The angular distribution for $3368\phantom{\rule{0.3em}{0ex}}\text{keV}$ $\ensuremath{\gamma}$ rays indicated the spin alignment of excited $^{10}\mathrm{Be}$ nuclei preferentially is parallel or antiparallel to their momentum.
