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 6He (n+n+α) and 11Li (n+n+9Li) 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.
