Studies of low-lying excited states in 12Be via inelastic scattering

In the neutron-rich region around N = 8, experimental evidence is being to accumulate that several neutron-rich nuclei, such as 11Li and 11Be, are strongly influenced by lowlying intruder orbitals [1,2]. In this neighborhood, 12Be is a typical neutron-rich nucleus with N = 8 , where the effects of shell quenching are most likely to be manifested. Since properties of low-lying states in even-even nuclei are sensitive to the modification of the nuclear shell structure, we have studied the low-lying E1 and E2 transitions of 12Be via inelastic scattering.
