Cluster model with core excitations. The Be-11 example
Artikel i vetenskaplig tidskrift, 2014

Bound states and low-lying resonances of the Be-11 one-neutron halo nucleus have been calculated within a two-body cluster model with core excitation. The lowest Be-10 core excited 2(+) state was considered as a quadrupole vibration. Shallow potentials were applied for neutron-core interaction, preventing motion in Pauli forbidden orbits. A good description of available experimental data including dipole excitations of Be-11 was obtained. For the bound 1/2(-) excited state the wave-function component gives the dominant contribution to the structure, which differs from results obtained in cluster models with deep potentials.
