Research Abstract |
Orthogonality condition model calculation of 4 alpha clusters was performed for 0+ states of 16O. The 6^<th> 0+ state was predicted as a 4 alpha Bose condensed state. Reproduction of data was good. GCM calculation with 4 alpha THSR wave functions incorporating resonance boundary condition also yielded 4 alpha Bose condensed state which has good correspondence with OCM result. Explanation was made about the large monopole strength between cluster-gas states and ground state.
