Three-body continuum energy correlations in Borromean halo nuclei. II

The general properties of intrinsic energy correlations in the three-body continuum of Borromean halo nuclei are considered. A model that describes the system as a three-body {alpha}+n+n cluster structure and reproduces the experimentally known properties of {sup 6}He and {sup 6}Li is used to study low-lying resonances and soft modes. The intrinsic correlated structure of the {sup 6}He continuum reveals a unique structure for three-body 2{sub 1}{sup +},2{sub 2}{sup +}, and 1{sub 1}{sup +} resonances and a lack of resonant structure in soft dipole and monopole modes.
