Forty states of ${}_{}{}^{84}{}_{}{}^{}\mathrm{Se}$ have been observed in the reaction ${}_{}{}^{82}{}_{}{}^{}\mathrm{Se}$(t,p), at a triton energy of 17 MeV. For most of them, $J^{\pi }$ values have been determined from the measured angular distributions. Excited states with $J^{\pi }$${=0\mathrm{}}^{+}$, $2^{+}$, and $4^{+}$ exhaust approximately 100% of the strength expected in a 2d(5/2, 3s1/2, 2d(3/2 space.
