Abstract

It is aimed to describe the nucleus of 9Be in an α-α-neutron cluster model, where the α-α and α-neutron interactions are determined via an effective field theory (EFT) for halo nuclei (halo-EFT). Here, only the α-α case is discussed more detailed and hence results are given for α-α phase shifts and for the ground-state energy of 12C as a three α cluster. The calculation of the 12C wave function is made via an expansion on nonsymmetrized hyperspherical harmonics (NSHH) in momentum space.
