The form factor for the 19.08-MeV level in oxygen-16 has been measured for momentum transfers between 60 and $260 \frac{\mathrm{MeV}}{c}$. The results, when compared with particle-hole calculations, strongly support an assignment $J=2\mathrm{}$. Since the transition is transverse, the parity is negative, and the assignment to the level is $J^{\pi }=2^{-}$.
