“…The ability to produce secondary beams of halo nuclei opened the possibility of investigating their structure by the measurement of the momentum distributions of the fragments coming out after a collision with stable nuclei [13][14][15][16][17][18][19]. The simplest approach to the understanding of Borromean nuclei fragmentation reactions was made by means of the sudden approximation [20][21][22], that assumes that one of the three particles in the projectile is instantaneously removed by the target, while the other two particles remain undisturbed.…”

The formalism to describe electron scattering reactions on two-neutron halo nuclei is developed. The halo nucleus is described as a three-body system (core+n+n), and the wave function is obtained by solving the Faddeev equations in coordinate space. We discuss elastic and quasielastic scattering using the impulse approximation to describe the reaction mechanism. We apply the method to investigate the case of electron scattering on 6 He. Spectral functions, response functions, and differential cross sections are calculated for both neutron knockout and α knockout by the electron.PACS numbers: 25.30. Fj, 25.70.Bc, 21.45.+v

“…This is a central assumption reflecting the reaction mechanism. It is discussed in previous publications and tested by comparison with experimental results [12,14,16,17,33,34]. The transition amplitude of the process in Fig.…”

“…The experimental data are taken from [9,16] for 6 He on C, and they are obtained at a beam energy of 400 MeV/nucleon and 240 MeV/nucleon, respectively. For 11 Li on C the experimental data are taken from [12,63] and they have been obtained with a beam energy of 280 MeV/nucleon. For 11 Li on Pb the data are from [12] and they correspond to a beam energy of 280 MeV/nucleon.…”

“…For 11 Li on C the experimental data are taken from [12,63] and they have been obtained with a beam energy of 280 MeV/nucleon. For 11 Li on Pb the data are from [12] and they correspond to a beam energy of 280 MeV/nucleon. Within this range of energies the difference in shape between the computed distributions is not visible.…”

“…In particular total dissociation cross sections and total interaction cross sections, as well as momentum distribution of the fragments after dissociation and after core breakup are available [7][8][9][10][11][12][13][14][15][16][17][18]. Different models describing these data have been developed.…”

We present in detail a theoretical model for fragmentation reactions of three-body halo nuclei. The different reaction mechanisms corresponding to the different processes are described and discussed. Coulomb and nuclear interactions are simultaneously included and the method is therefore applicable for any target, light, intermediate and heavy. Absolute values of many differential cross sections are then available as function of beam energy and target. We apply the method to fragmentation of 6 He and 11 Li on C, Cu and Pb. A large variety of observables, cross sections and momentum distributions, are computed. In almost all cases we obtain good agreement with the available experimental data.
