Abstract
We study the ^99Be
ground-state energy with non-local \alpha nαn
and \alpha \alphaαα
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 ^99Be
with the Lorentz Integral Transform (LIT) method.
