A new model for the 4He nucleus which combines properties of the shell and face‐centered‐cubic (FCC) models is introduced. The model limits excitation to a single nucleon, and the interaction strengths for the excited states are derived from the Sussex matrix elements and the FCC ground‐state interaction parameters. The resulting excited states provide a reasonable description of the levels of Fiarman and Meyerhof. For example, the 20.1 MeV first excited state is predicted to be a 2 w single particle excitation out of the 4He FCC core. Although the initial results are encouraging, some further adjustments to the model are necessary.
