摘要：

A new method to calculate the low-lying states of light nuclei is proposed: Antisymmetrized Molecular Dynamics (AMD) - Superposition of Selected Snapshots (AMD triple-S). In addition to the cluster features of the core nucleus, the properties of the wave of the valence nucleons are well expressed in terms of a superposition of selected AMD wave functions. Our previous results based on Molecular-orbits are justified using this new framework. For example, the three 0(+) states of Be-10 are found to be well described. Here, the importance of solving the cooling equation for the imaginary part of the Gaussian centers for the nucleons is examined. For Be-12, the newly observed J = 0 state at 2.24 MeV is analyzed to be the second 0(+) state. The method is further applied to Ne isotopes with 5alpha-core, and parity mixing of the single-particle orbit around parity- asymmetric core is discussed.
