Coulomb and nuclear breakup of three-body halo nuclei

Abstract

We investigate dissociation reactions of loosely bound and spatially extended three-body systems. We formulate a practical method for simultaneous treatment of long-range Coulomb and short-range nuclear interactions. We use ${}^6$He (n+n+$\alpha$) and ${}^{11}$Li (n+n+${}^9$Li) as examples and study the two-neutron separation cross sections as functions of target and beam energy. Individual Coulomb and nuclear as well as interference contributions are also extracted.
