抄録

The nuclear-breakup and Coulomb-breakup contributions to ^6Li → α + d and ^7Li → α + t breakup reactions which are used to access to the radiative capture reactions important in nuclear astrophysics are investigated by three-body calculations with the use of the realistic cluster-model wave functions for the bound and unbound states of ^6Li and ^7Li. For incident energies well above the Coulomb barrier, the nuclear-breakup contribution is as important as the Coulomb-breakup one up to forward angles where the Coulomb breakup was believed to be dominant. The effects of multi-step processes via various nonresonant continuum states due to the three-body dynamics are also found to be important. On the other hand, at sub-barrier energies the Coulomb-breakup contribution dominates over the nuclear-breakup one and the effect of multi-step process may be factored out.
