Nuclear breakup of 8 B in a direct fragmentation model ∗
We calculate the cross sections of the elastic and inelastic breakup modes for the inclusive breakup reaction 28Si(8B,7Be) at beam energies between 10 40 MeV/nucleon within a direct fragmentation model formulated in the framework of the post form distorted-wave Born-approximation. In contrast to the case of the stable isotopes, the inelastic breakup mode is found to contribute only up to 30% to...
متن کاملLi direct breakup lifetimes
α-d coincidence data were studied for the Li + Co reaction at Elab = 29.6 MeV. By using a kinematic analysis, it was possible to identify which process, leading to the same final state, has the major contribution for each of the selected angular regions. Contributions of the Li sequential and direct breakup to the incomplete fusion/transfer process were discussed by considering the lifetimes ob...
متن کاملGrand Canonical Model Predictions For Nuclear Fragmentation
A very simple but very popular model for nuclear multifragmentation is this: the nucleus is heated up and breaks up into many pieces (composites and new produced particles if the energy is sufficient) strictly according to phase space. This occurs in an expanded volume, about three or four times the normal volume. Population strictly according to phase-space implies chemical and thermal equilib...
متن کاملNuclear Breakup of Borromean Nuclei
We study the eikonal model for the nuclear-induced breakup of Borromean nuclei, using 11Li and 6He as examples. The full eikonal model is difficult to realize because of six-dimensional integrals, but a number of simplifying approximations are found to be accurate. The integrated diffractive and onenucleon stripping cross sections are rather insensitive to the neutron–neutron correlation, but t...
متن کاملMechanisms for Direct Breakup Reactions
We review some simple mechanisms of breakup in nuclear reactions. We mention the spectator breakup, which is described in the post-form DWBA. The relation to other formulations is also indicated. An especially important mechanism is Coulomb dissociation. It is a distinct advantage that the perturbation due to the electric field of the nucleus is exactly known. Therefore firm conclusions can be ...
