Exploring the Structure of the Most Neutron-rich Boron and Carbon Isotopes

The most neutron-rich isotopes of boron and carbon are of considerable interest in terms of their few-body character - most notably through the possible formation of twoneutron haloes in the Borromean nuclei 19B and 22C. Here a series of recent investigations are briefly reviewed, including prelimin...
