The intermediate-coupling transition of the five lowest levels of Li 7 -Be 7 is discussed. Some analytical emphasis is placed on tie approach from the (jj) coupling extreme with ordinary (nonexchange) interactions, in which case there is a first-order degeneracy which might have helped explain the scarcity of low levels, but second-order perturbations are shown to be too large. The only possibility of obtaining just two isolated low levels with either ordinary or Majorana interactions lies near the (LS) coupling extreme, with angular momentum /= 1/2 for the excited state.
