Study of Resonant States in Halo Nuclei
A strategy for theoretical study of neutron halo nuclei is proposed: At the first stage (I), we solve a few-body problem of the core-plus-neutron model assuming a single frozen configuration for the core cluster. At the second stage (II), we take into acc

Foreword
This volume contains the proceedings of the International Workshop on Resonances in Few-Body Systems held in Sarospatak, at the Tokaj wine area, Hungary, from 4 to 8 September, 2000. Resonances belong to the most widespread natural phenomena. They occur in systems ranging from macroscopic elastic bodies to systems of elementary particles. Any system that has eigenfrequecies and is coupled to its environment can show resonances. A resonance may be considered an eigenstate of a system. Although it has a finite life-time, the eigenstate concept can be formulated precisely even in quantum mechanics, as a kind of generalization of the quantum mechanical notion of an eigenstate. The very word 'eigenstate' suggests that the properties of these states are characteristic of the system itself: of its composition, size, number of degrees of freedom, excitation mecha
