| 英文摘要 | The existence of the 0(3)(+) and 0(4)(+) states around 10 MeV excitation energy in C-12 is confirmed by a fully microscopic 3 alpha cluster model. Firstly, a generator coordinate method (GCM) calculation is performed by superposing optimized 2 alpha + alpha Tohsaki-Horiuchi-Schuck-Ropke (THSR) wave functions with the radius-constraint method. The obtained two excited 0(+) states above the Hoyle state are consistent with the recently observed states by experiment. Secondly, a variational calculation using the single 2 alpha + alpha THSR wave function orthogonalized to the ground and Hoyle states is made and it also supports the existence of the 0(3)(+) state obtained by the GCM calculation. The analysis of the obtained 0(3)(+) state is made by studying its 2 alpha-alpha reduced width amplitude, its 2 alpha correlation function, and the large monopole matrix element between this state and the Hoyle state, which shows that this 0(3)(+) state is a breathing-like excited state of the Hoyle state. This character of the 0(3)(+) state is very different from the 0(4)(+) state which seems to have a bent-arm 3 alpha structure. |
