The photodisintegration of 6Li and 7Li

The photodisintegration of the stable Lithium isotopes has been investigated by spectroscopy of the emitted charged particles using the Giessen bremsstrahlung facility. Protons, deuterons, tritons, 3He and alpha particles were detected and identified up to 20 MeV particle energy. Angular distributions were measured using γ-ray energies up to Esub(γ) = 50 MeV. They are compared with theoretical predictions and with other experiments. A remarkable low (γ,t)-cross section was found for both isotopes in disagreement to previous mesurements using virtual photons. Coincidence measurements between the emitted particles were performed in order to study the manybody-breakups of 7Li. (orig.)
