  We study the 9 Be ground-state energy with non-local ${\alpha}-$n and
${\alpha}-{\alpha}$ potentials derived from Cluster Effective Field Theory. The
short-distance dependence of the interaction is regulated with a momentum
cutoff. The potential parameters are fitted to reproduce the scattering length
and effective range. We implement such potential models in a Non-Symmetrized
Hyperspherical Harmonics (NSHH) code in momentum space. In addition we
calculate ground state energies of various alpha nuclei. Work is in progress on
a calculation of the photodisintegration of 9Be with the Lorentz Integral
Transform (LIT) method.
