Resonance and continuum states in weakly bound systems
Linear response theories in the continuum capable of describing continuum
spectra and dynamical correlations are presented. Our formulation is
essentially the same as the continuum random-phase approximation (RPA) but
suitable for uniform grid representation in the three-dimensional (3D)
Cartesian coordinate assuming no spatial symmetry. Effects of the continuum are
taken into account either by solving equations iteratively with a retarded
Green's function or by an absorbing boundary condition. The methods are applied
to giant resonances in a deformed nucleus 12C.Comment: Talk at 7th Internaltional Spring Seminar on Nuclear Physics
