Strong coupled-reaction-channel scheme with the hybridization of the valence nucleon in the 12C+13C system

It is confirmed that the strong coupled-reaction-channel effects observed in the system of 12C+13C(gr.1/2-;3.086MeV,1/2+; 3.854MeV,5/2+) are due to the hybridization between the 1p1/2 and the ''reoriented'' 1d5/2 orbitals of the valence neutron. The transfer processes play an essential role in the hybridization. This scheme is little influenced by the binding energies of the single particle states and is not affected by the absorption part of the optical potential between the two core nuclei. (author)
