Exotic nuclei, short lived radioactive isotopes, are an ideal laboratory to study the strong- and weak interaction at play in the nuclear medium. Especially their unusual proton-to-neutron ratio allows validating and improving state-of-the-art nuclear models.
An intriguing part of the nuclear-structure of exotic nuclei deals with the delicate interplay between the individual nucleon motion and the collective nucleus behavior. The ISOLDE facility at CERN produces a large variety of exotic nuclei and offers unique opportunities for laser spectroscopic, decay and Coulomb excitation studies.
Distinctive features of the facility, like resonant laser ionization, will be presented and recent physics highlights obtained in the neutron-deficient lead isotopes will be discussed.
