Abstract :

With the advent of the new radioactive beam facilities that aim at probing the structure of atomic nuclei at, or near, the drip-lines, nuclear models must be extended to incorporate fully the effects of the continuum. Indeed, nuclei with a large excess of neutrons (or protons) are often very weakly-bound, and the particles in the last occupied levels can be scattered by any residual interaction (such as e.g. pairing) into the continuum of positive energy states. The talk will review the various possible strategies that have been implemented to treat continuum effects at a mean-field level. It will also discuss a new method based on the construction of a special single-particle basis that aims at replacing the standard harmonic oscillator basis while embedding continuum effects.
