Measurement of the absolute and differential cross sections for <sup>7</sup>Li(γ,n<sub>0</sub>)<sup>6</sup>Li

We have measured the cross section of the photoneutron reaction channel 7Li + γ → 6Li (g.s.) + n where the progeny nucleus is the ground state of 6Li. We obtained the absolute cross section at photon energies 10, 11, 12, 13, 15, 20, 25, 30, and 35 MeV and also the dependence of the cross section on polar angle for all but the highest photon energy. For the energies 10 to 15 MeV we were able to use linearly polarized photons to obtain the dependence of the cross section on the photon polarization.
