Abstract

The scattering of a weakly bound three-body system by a target is discussed. A transformed harmonic oscillator basis is used to provide an appropriate discrete and finite basis for treating the continuum part of the spectrum of the projectile. The continuum-discretized coupled-channels framework is used for the scattering calculations. The formalism is applied to different reactions, He6+C12 at 229.8 MeV, He6+Zn64 at 10 and 13.6 MeV, and He6+Pb208 at 22 MeV, induced by the Borromean nucleus He6. Both the Coulomb and nuclear interactions with a target are taken into account.
