We have measured the energy and angle of coincident $\mathrm{np}$ pairs from the reaction ${}_{}{}^6{}_{}{}^{}\mathrm{Li}(\gamma ,np)\alpha$ with 67-MeV bremsstrahlung. Quasideuteron correlations were observed as a function of photon energy. The measured quasideuteron transverse momentum distribution was fitted with a $2S$ harmonic-oscillator momentum wave function, yielding a full width at half maximum of 89.4 ± 5.6 MeV/c. Coincident $\mathrm{np}$ events from the reaction ${}_{}{}^6{}_{}{}^{}\mathrm{Li}(\gamma ,p){}_{}{}^5{}_{}{}^{}\mathrm{He}$ were also observed.
