【 摘 要 】

The structure of the light exotic nucleus8B is investigated in the Fermionic Molecular Dynamics (FMD) model. The decay of8B is responsible for almost the entire high- energy solar-neutrino flux, making structure calculations of8B important for determining the solar core temperature.8B is a proton halo candidate thought to exhibit clustering. FMD uses a wave-packet basis and is well-suited for modelling clustering and halos. For a multiconfiguration treatment we construct the many-body Hilbert space from antisymmetrised angular-momentum projected 8-particle states. First results show formation of a proton halo.
