The differential cross section for the elastic scattering of protons by ${\mathrm{Li}}^6$ is presented at energies from 2.4 to 12 MeV and laboratory angles from 33.8° to 160°. A resonance appears strongly at backward angles at incident proton energy of 5 MeV suggesting the existence of a level in ${\mathrm{Be}}^7$ at approximately 10 MeV. The possibility of this level being a ${}_{}{}^4{}_{}{}^{}P$ state in ${\mathrm{Be}}^7$ is discussed.
