Research Abstract |
Alpha-particle condensate is a novel state in nuclei. The possibility of their existences has been theoretically explored in ^<16> O,^<11> B, and ^<13> C. It was found that they appear around 4alpha, 2alpha+triton, and 3alpha+neutron breakup thresholds, respectively. Isoscalar monopole transition strengths are very useful to search for cluster states in light nuclei, and we have clarified the mechanism of why the cluster states are relatively strongly populated from the mean-field-like ground state through the isoscalr monopole transition.
