Résumé :

The 9,10,11 Be nuclei are described in a microscopic multicluster model involving α + α + n, α + α + n + n and α + α + n + n + n configurations, respectively. The effect of α clustering is shown to decrease from 9Be to 11Be. In 9Be, we find 1/2+, 1/2- and 3/2- bands which are well supported by experimental data. For 10Be, in addition to the ground-state band, we predict 1+ and 1- rotational bands; α + 6He cluster states are also discussed. A 1/2+ band is obtained in 11Be, but negative-parity states do not present significant clustering. The existence of a 3/2- band, suggested recently, is therefore not supported by the model. © 2002 Elsevier Science B.V. All rights reserved.
