A REPRESENTATION TO DESCRIBE NUCLEAR PROCESSES IN THE CONTINUUM

Bound single-particle states, outgoing resonances and a limited number of scattering states along a path in the complex kappa-plane (Berggre n space) are used as a representation to describe the eigenstates of a realistic nuclear Hamiltonian. It is found that these eigenvectors ar e contained in the Berggren space, i.e. that the diagonalization of th e Hamiltonian provides all the bound states and resonances while the r est of the eigenvalues still remain on the same complex path.
