Molecular structures in two- and three-centre systems

Some recent studies of clustering in carbon and beryllium isotopes using break-up reaction studies are reported. Studies of the ⁷Li(⁹Be,⁹Be+α) and ⁷Li(⁹Be,¹⁰Be+α) reactions provide an insight into clustering in three-centre systems. Similarly, neutron knockout reactions involving the 4n removal channel with a ¹²Be projectile may provide an insight into the nature of molecular states in two-centre systems.
