Microscopic calculations of low energy alpha neutron scattering are reported for the resonant $J^{\pi }$${=(1/2\mathrm{}}^{\mathrm{-}}$ and ${(3/2\mathrm{}}^{\mathrm{-}}$ states. A good qualitative fit to the experimental L⋅S splitting is obtained, although discrepancies of the order of 1–2 MeV remain. Results with two different nucleon-nucleon interaction models are presented, and the effects of three-nucleon interactions are discussed.
