In the model the total orbital momentum is fixed for each energy level. Thus each level is determined as a member of the spin-flip doublet corresponding to the total orbital momentum ($L^\\pi=0^+, 2^+,4^+, 1^-, 2^-,3^-, 4^-$) of the system. The Ali-Bodmer potential (model E) is applied for the $\\alpha\\alpha$ interaction. We employ a local $\\alpha n$ potential which was constructed to reproduce the $\\alpha-n$ scattering data.
