The reaction ${\mathrm{F}}^{19}(p, \gamma ){\mathrm{Ne}}^{20}$ has been studied at two resonances, 669 kev and 1092 kev, to obtain information about properties of the 4.97-Mev level in ${\mathrm{Ne}}^{20}$. It is shown that this 4.97-Mev level is fed by a direct transition from the 1+ resonance at 669 kev, that it does not have spin 0 and that its transition to the ground state of ${\mathrm{Ne}}^{20}$ is less than 5% of the transition to the first excited state. It is concluded that the most likely assignments to the 4.97-Mev level are 2± or 3+.
