| Research Abstract |
It is well established that a quantum condensation composed of gas-like alpha particles, which is a new type of nuclear structure, is realized in the second 0^+ state in ^<12>C and the sixth 0^+ state in ^<16>O. In this study, we showed that the gas-like cluster states are realized in a wider region, such as in non-zero spin states in ^<16>O and in light lambda hypernuclei. We further showed that the cluster-type-mean-field structure, which is a basic idea to understand the αcluster condensates, is realized in non-gas-like ordinary cluster-structure states.
