摘要：

The extraction of the photodissociation cross sections of B-8 from Coulomb dissociation experiments is investigated. A careful study is done on the contributions of the El, E2 and M1 multipolarities to the breakup. A comparison with the data of a recent experiment is performed. It is shown that the extraction of the radiative capture cross sections Be-7(p,gamma)B-8 which are relevant for the solar neutrino problem is not affected appreciably by Coulomb reacceleration. A non-perturbative model is used for the purpose. Emphasis is put on the perspectives for future experiments which are planned at the University of Notre Dame, RIKEN (Japan) and GSI (Germany). An analysis of the total yields of ''photon-point'' processes in inelastic electron scattering is also done.
