Five-body calculation with Pauli constraint for shell- and cluster-structure in 16O
A 12C+four-nucleon (4N) five-body model is applied for the ground and first excited states of 16O. The 4N configurations are selected in a wide Hilbert space under the fulfillment of the Pauli principle excluding the occupied orbits in 12C. The energies of both the states are obtained in excellent a...

| description | A 12C+four-nucleon (4N) five-body model is applied for the ground and first excited states of 16O. The 4N configurations are selected in a wide Hilbert space under the fulfillment of the Pauli principle excluding the occupied orbits in 12C. The energies of both the states are obtained in excellent agreement with experiment. Analysis of the wave functions indicates a spatially localized alpha-particle-like cluster structure for the excited state and a shell-model-like delocalized structure for the ground state. The difficulty of describing the cluster structure by a standard shell model approach is discussed by calculating components of the harmonic-oscillator quanta in the wave functions. |
