Abstract.
The presence of an anomaly in binding energies for the “island of inversion” centered at Z = 11, N = 21 is obtained by comparison of macroscopic binding energies and experiment. The macroscopic calculations were done with a mass formula deduced from the reformulation of the liquid-drop model of Myers et al. ; this formula is described in detail such as its predictions for binding energies of neutron-rich A = 29-44 nuclei. These calculations have indicated the presence of anomalies in the “island of inversion”. A weak-coupling approximation is applied to study this deformed region. The binding-energy values obtained using this model show the absence of these anomalies.
