摘要：

The intermediate structure seen in some heavy-ion reactions is described by the fragmentation of a quasi-molecular shape resonance through coupling to at least two exit doorway states. We investigate particularly the correlated structures observed in the γ, p, n, d and α reaction channels for the system 12C-12C around Ec.m. = 19.5 MeV. Within the framework of the continuum shell model of Mahaux and Weidenmüller we are able to describe qualitatively the observed excitation functions in the elastic and reaction channels, assuming a spin assignment of 12+ for the gross structure. © 1979.
