Resumen:
The heavy beryllium isotopes 13Be and 14Be are described as one- and two-neutrons outside of a deformed 12Be
core, which is treated as a rigid rotor and the neutroncore
interaction is approximated by a deformed WoodsSaxon potential. Our
three-body description of 14Be uses the hyperspherical
expansion formalism, including the core degrees of freedom. We explore
those potential parameters compatible with the known properties of 12Be, 13Be and 14Be. We find that both 14Be and 13Be can be described simultaneously provided the 12Be core has a large positive quadrupole deformation.
