| Abstract: | Direct and sequential break-up of 7Li projectiles in the field of heavy target nuclei are studied on the basis of the Coulomb excitation approach. It is found that the experimental data observed for forward emission angles are fairly well described by Coulomb effects and that for angles more forward than 12° the direct (E1) break-up or 70 MeV7Li scattered from 120Sn exceeds considerably the resonant (E2) break-up mode via the 7−/2 state in 7Li at Ex = 4.63 MeV. |
