Outline of Final Research Achievements

By using the extended version of the THSR wave function, we studied the emergence of gaslike clsuter states and other cluster structure states in several nuclei including Lambda hyperon, such as 12C,16O,9ΛBe, and 13ΛC. In particular, in 12C, two mmysterious 0+ state located above the famous Hoyle state, the second 0+ state, and the so-called Hoyle band states (2+,4+ states) are investigated and the essential physics of them was clarified. The third 0+ state was shown to be monople-like excitation from the Hoyle state. The fourth 0+ state was shown to have 3-alpha linear-chain structure. In Lambda hyper nuclei, it was shown that the cluster correlation is crucially important.
