EXCITATION-FUNCTIONS FOR THE 2-NUCLEON PHOTOABSORPTION IN LI-6

The Li-6(gamma,np) and Li-6(gamma,pp) reactions have been studied usin g tagged photons in the range 114 < E(gamma) < 600 MeV. Excitation fun ctions and missing energy spectra are presented. The simple structure of Li-6 and kinematical constraints are exploited to determine the rel ative importance of the various photoabsorption mechanisms. The genuin e two-nucleon absorption can be identified up to photon energies of 50 0 MeV and is found to be most important at low missing energies. The L i-6(gamma,np) data are well reproduced by predictions of a quasideuter on model.
