Band structures in light neutron-rich nuclei

Abstract

The structure of beryllium isotopes in the mass range A 8 12 has been investigated using the properties of different bands, which are populated in specific reactions. The different structures are formed in transfer reactions with neutron stripping on 9,10Be or proton pick up on on 12,13,14C. The slope in the linear dependence of the excitation energies on J J 1 , where J is the spin, has been deduced for 13 bands and compared for common systematics. From the measured moments of inertia the distance has been deduced for molecular structures
