| 英文摘要 | The Efimov (Thomas) trimers in excited C-12 nuclei, for which no observation exists yet, are discussed by means of analyzing the experimental data of Zn-70(64)(Ni-64) + Zn-70(64)(Ni-64) reactions at the beam energy of E/A = 35 MeV/nucleon. In heavy ion collisions, alpha-particles interact with each other and can form complex systems such as Be-8 and C-12. For the 3 alpha-particle systems, multi-resonance processes give rise to excited levels of C-12. The interaction between any two of the 3 alpha-particles provides events with one, two or three Be-8. Their interfering levels are clearly seen in the minimum relative energy distributions. Events with the three alpha-particle relative energies consistent with the ground state of Be-8 are observed with the decrease of the instrumental error for the reconstructed 7.458 MeV excitation level in C-12, which was suggested as the Efimov (Thomas) state. |
