The structure of the three-body Borromean nucleus {sup 6}He is approximated by a two-body di-neutron cluster model. The binding energy of the 2n-{alpha} system is determined to obtain a correct description of the 2n-{alpha} coordinate, as given by a realistic three-body model calculation. The model is applied to describe the breakup effects in elastic scattering of {sup 6}He on several targets, for which experimental data exist. We show that an adequate description of the di-neutron-core degree of freedom permits a fairly accurate description of the elastic scattering of {sup 6}He on different targets.
