title: Microscopic calculation of six-body inelastic reactions with complete final state interaction: photoabsorption of (6)He and (6)Li.
abstract: Six-body inelastic reactions are calculated microscopically including the full six-nucleon final state interaction. The total cross sections of gamma+ (6)He ( (6)Li)-->X are considered as examples. The Lorentz integral transform method and the effective interaction approach for the hyperspherical formalism are employed. While (6)Li has a single broad giant resonance peak, there are two well separated peaks for (6)He corresponding to the breakup of the neutron halo and the alpha core, respectively. The comparison with the few available experimental data is discussed.
