摘要：

We calculate the longitudinal and transverse momentum distributions of the fragments Li-9, Be-10 and Be-12 emitted in the reactions induced by the neutron rich nuclei Li-11, Be-11 and Be-14 respectively on several targets at different beam energies within a direct fragmentation model. For all the cases, the shapes of the longitudinal momentum distributions are found to depend very weakly on the interactions governing the fragmentation. However, both widths and the absolute magnitudes of the transverse momentum distributions are sensitive to the fragment-target interactions. Comparisons with the recent experimental data are made to support our conclusions.
