Outline of Final Research Achievements

The basic aim of this research project was to certificate that a single THSR (Tohsaki-Horiuchi-Schuck-Roepke) wave function which describes spatially nonlocalized clustering can well describe all sorts of cluster states. This aim was achieved successfully for several representative cluster states. The THSR wave function was generalized so as to express the more than one containers. The cluster states which were studied were Hoyle state, breathing excited state of the Hoyle state, 3-alpha bent-arm states, 3-alpha and 4-alpha linear-chain states, the ground and excited states of neutron-rich nuclei 9Be and 10Be, and so on.
