摘要
An alpha-cluster model is proposed for Be-8 and C-12 nuclei, within the framework of the resonating group method (RGM). The composing He-4 clusters are described using Jastrow-correlated translationally invariant configuration-interaction (Jastrow-TICI2) wave functions. The ground-state energies of the nuclei are computed by means of a Metropolis Monte-Carlo sampling. (C) 2001 Elsevier Science B.V, All rights reserved.
