چکیده

We describe a reaction mechanism which is consistent with all available experimental information of high energy three-body breakup processes. The dominating channels are removal of one of the three halo particles leaving the other two either undisturbed or absorbed. We compare with the commonly used deceptive assumption of a decay through two-body resonance states. Our predictions can be tested by measuring neutron-neutron invariant mass spectra.

Momentum distributions and reaction mechanisms for breakup of two–neutron halos

A theoretical model able to describe fragmentation reactions of three–body halo nuclei on different targets, from light to heavy, is used to compute neutron and core momentum distributions. Both Coulomb and nuclear interactions are simultaneously included. We specify the different reaction mechanisms related to various processes. The method is applied to fragmentation of 6He and 11Li on C and P...

Nuclear 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...

Two-neutron removal reactions of He treated as a three-body halo

We formulate a method to compute breakup processes of three-body halo systems reacting with a target. The reaction between one of the particles and the target as well as the corresponding pairwise final state interactions are carefully treated. Both absorption and diffraction processes are included. Detailed differential and total cross sections are calculated for two-neutron (2n) removal from ...

Coulomb breakup mechanism of neutron-halo nuclei in a time-dependent method.

The mechanism of the Coulomb breakup reactions of the nuclei with neutronhalo structure is investigated in detail. A time-dependent Schrödinger equation for the halo neutron is numerically solved by treating the Coulomb field of a target as an external field. The momentum distribution and the postacceleration effect of the final fragments are discussed in a fully quantum mechanical way to clari...

Fusion and Direct Reactions of Halo Nuclei at Energies around the Coulomb Barrier

The present understanding of reaction processes involving light unstable nuclei at energies around the Coulomb barrier is reviewed. The effect of coupling to direct reaction channels on elastic scattering and fusion is investigated, with the focus on halo nuclei, for which such effects are expected to be most important. With the aim of resolving possible ambiguities in the terminology a short l...
