Exploring the structure of the most neutron-rich Boron and Carbon isotopes

Abstract : 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 preliminary results from reaction studies of 18B and 21C. It is concluded that 22C exhibits a prominent halo arising from a significant ν2S1/22 valence neutron configuration. More generally, the structure of the dripline boron and carbon nuclei appears to be governed by the competition between the ν1d5/2 and ν2s1/2 single-particle orbitals, with a 5/2+ – 1/2+ level inversion very probably occuring in 21C.
