Nuclear Clustering Quest in Relativistic Multifragmentation

The status of nuclear clustering studies performed by nuclear emulsion irradiations in beams of light relativistic nuclei is briefly reviewed. Thanks to the best spatial resolution and full solid angle acceptance provided by nuclear emulsions, such an approach allows one to obtain a unique and evident observations reflecting cluster-like features in light nuclear structures. Future investigations are suggested in relativistic beams of He, Be, B, C, and N isotopes.
