【 摘 要 】

Properties of some12C resonant states at low energies are studied in three-α- particle model. Calculations for breakup reactions of12C bound state leading to three-body continuum states are performed at energies up to a few MeV above the breakup threshold by applying the Faddeev three-body formalism in coordinate space. Calculated cross sections reveal some resonant peaks. Decay modes and the structure at interior region of these resonant states as well as their effects on the triple-alpha reaction rate will be reported.
