The 7Li total photoabsorption cross section is calculated microscopically, using the semi-realistic AV4' as nucleon-nucleon potential. The interaction of the final 7-nucleon system is fully taken into account via the Lorentz Integral Transform (LIT) method. For the calculation of the LIT we use expansions in hyperspherical harmonics (HH) in conjunction with the effective interaction (EIHH) approach. The calculated cross section agrees quite well with the available experimental data in an energy range from threshold up to 100 MeV.
