报告摘要:Wereport our recent progress on the multi-configuration description of lightnuclei with a new variational scheme. We employ a nuclear model of theantisymmetrized molecular dynamics (AMD) and superpose the AMD Slaterdeterminants to describe the total wave function. All the parameters in themultiple AMD basis states are determined according to the variational principleof the total energy, which means the simultaneous optimization of the multipleAMD bases. We further extend the method to describe the excited states imposingthe orthogonality to the ground-state configurations. We show the results oflight nuclei of He, Li and Be isotopes, in which we confirm not only theshell-model like states but also the cluster states with various partitionsincluding the alpha particle and triton. We also predict the elongatedlinear-chain structures in the excited states of 9Li and 10Be with N=6isotones. We further report the preliminary results of A=4N nuclei, 12C, 16Oand 20Ne and the multi alpha-cluster states are confirmed in their excitedstates.
