The CRIS (Collinear Resonance Ionization Spectroscopy) experiment at CERN ISOLDE is joining together the high resolution of collinear laser spectroscopy with the high efficiency and selectivity of resonant ionization. It is used to study the ground-state properties of exotic nuclei, such as spins, nuclear moments and shapes, and to produce beams of high isomeric purity for dedicated decay studies.

For more details about the CRIS experiment see the article published in Nuclear Physics News entitled "CRIS: A New Sensitive Device for Laser Spectroscopy of Exotic Nuclei".
