We investigate the six resonances above the break-up threshold and below 6 MeV: $1/2^\\pm$, $3/2^\\pm$ and $5/2^\\pm$. The short-distance properties of each resonance are studied, and the different angular momentum and parity configurations of the $^8$Be and $^5$He two-body substructures are determined. We compute the branching ratio for sequential decay via the $^8$Be ground state which qualitatively is consistent with measurements.
