Wide-angle alpha-t coincidence measurement in the breakup of Li-7 on Al-27

We have performed wide-angle in-plane coincidence measurements of the alpha particles and tritons emitted in the 48-MeV Li-7 projectile breakup reacti on on Al-27. The data have been analyzed using the post-form distorted-wave Born-approximation (DWBA) theory of breakup reactions where Coulomb and nu clear breakup as well as their interference terms are included. The theory is able to provide a good description of the experimental data particularly at large relative angles between the fragments. The interference between t he Coulomb and nuclear breakup modes is found to be significant.
