Description

Excited states of 11Be have been studied with several transfer reactions. Nine states between 3.96 and 25.0 MeV excitation energy show the characteristic energy dependence of a rotational band. The deduced large moment of inertia is consistent with a 2α structure with large deformation. In 12Be four high-lying states observed at 7.3, 10.7, 14.6, and 21.7 MeV in the reaction 9Be(15N,12N)12Be, also form a rotational band with almost the same moment of inertia; tentative spin assignments of 2+-8+ are used
